When i try playing minecraft it just craches after a minute or so. it says it needs more memory but i already gave it 20 gigs. do i need to give it more or is this something linux related?

I'm kinda new with Linux, I've been using it for a while now (like a couple months) but I'm very happy with it, but, I've seen some differences about the temperature of my laptop compared to Windows 11 and I'm wondering if these numbers on screen are my actual temperatures.

I know that a very noticeable Linux advantage over Windows is that it uses way less resources, specially compared to W11, and that Laptops get way more hot than usual desktop PCs, but while I was playing RDR2 I noticed that I was getting around 20 C° less or even more compared to Windows.

My laptop is not even close the best in the market and I know that (3050ti, i5-11400H, 16gb Ram), plus the usual problems with Nvidia graphics cards, but I can't stop thinking about this, are these temps real? Is this the "Linux advantage" I mentioned earlier? Am I going crazy because of a problem that is only in my head?

In the picture you can see that I'm getting about 66°, and the temp in the top right corner shows 71° (that's the Cpu). Usually when playing modern and very demanding games (at least for my graphics card) I used to get up to 87° easily on Windows, specially something like RDR2 which made my Laptop sound like it was about to fly thanks to the fans spinning so fast, and not only that, I was also streaming the game and playing it in my phone while in bed this time.

Please just clear my mind.

(By the way, I lowered the resolution for a moment and used borderless window just to take the screenshot, I was playing at 1080p 60fps Fullscreen, the transmission had the same settings)

Hi

So I have just seen that BF6 requires kernel level anti-cheat.

This is expected but still irritating and sad.

My PC have 2 SSDS, the primary is Fedora KDE linux, and the second disc contains Windows 11 for games like BF1 and now the upcoming BF6

Now BF6 states that it need secure-boot.

I do not have secure-boot enable right now,

can I have secure-boot enabled with the separate disc dual-boot setup ?

Is there any downsides in having secure-boot enabled ?

and lastly, Does kernel level anti-cheat from the windows disc compromise the security of my Fedora disc install ?

thanks

Games on new install of Hyprland with archinstall script hitch and stutter. (installation made today)

here is the pastebin of my hyprland.conf = https://pastebin.com/Lhp5CKDb

I have set up hyprland and read the wiki many times but cannot seem to get games, in this case, cyberpunk on update 2.3 from steam to run well, it keeps hitching and stuttering with very low 1% lows and single digit 01% lows.
Here are my specs:
R7 9800x3D
RTX 5090 Gamerock OC
64GB 6400MT/s CL32 ram
swap is set to 66GB
2x4TB 990 PRO
1x4TB SP XS70
1x4TB WD Black SN850x
OS and cyberpunk are installed on the WD black drive, which was purchased in June 2025.
Nvidia driver version is 575.64.05 checked with Nvidia-smi

Monitor is a G9 Oled 240hz connected via DP

I have not tried other games yet as things are still installing, I have tried to precache vulkan shaders on steam to no avail, the precaching freezes at 85% even after trying to force steam to use 10 threads whilst doing it in the steam_dev.cfg file I created.
Please help as I do not want to go back to windows.

So whenever I launch Rocket League, I can get to the title screen and SFX plays, but whenever I press a button, the screen fades to black and then the game stops responding.

I've tried it with Proton GE and Proton-Hotfix from Steam but nothing. Anybody know why?

I'm running this on an RX580 btw.

I asked for a recommendation on a gpu a couple weeks ago and the answer was overwhelmingly the 9060xt, however it doesn’t work natively with Mint. I was wondering if anyone has any experience with Kubuntu.

I like the idea of having a reliable distribution with lots of tutorials considering I’m relatively new. I’ve been running Bazzite OS but it’s hard to find tutorials for running services as this is also a homelab (why I like the idea of having a reliable distribution).

Skip to the results if you want a tldr.

Intro

Hello all, I’ve semi-recently switched to Linux full time and have been happy with it however I’ve noticed what I perceived to be a small increase in input latency despite performance being the same as far as I could tell. So I decided to do some testing. But not the camera pointed at a monitor method. You’ve perhaps seen Nvidia’s LDAT that takes a mouse button click and a sensor physically on the monitor to compare the latency between the click and the light coming from an action, usually a muzzle flash. However, that's expensive to buy so I built my own with an arduino. I would post the code but because I was distro hopping I forgot to backup the sketch and it’s gone. But it’s still on the arduino so I can still use it.

How It Works

I have an arduino starter kit that comes with a button and a phototransistor. I also have a Logitech G903 that I took apart and connected the left mouse button to a button attached to the arduino. The mouse button outputs 3.3v and shorts when the button is clicked causing the mouse to register a click. So the arduino loops checking for when the mouse button output goes LOW. It then goes into a while(true) loop that checks the phototransistor and breaks the loop when the value from the transistor is high enough. It stores the time when the button is pressed and when the transistor reaches a high enough value then outputs the result in the serial monitor. You may be asking if the arduino is fast enough to do this without adding latency of its own that matters. I think it is plenty fast from my own testing. I found a script that tested how many times the main loop executed per second and it was in the 10s of thousands or over 10,000Hz even with all my code added. That would be nanosecond response times. If I hold a flashlight on the transistor and press the button it outputs 0ms consistently. I think the arduino is plenty fast to check the latency. I then hold the phototransistor up to the screen in front of the barrel of a gun. I chose overwatch 2 because of it’s kind of dark practice room and mcree’s gun having a large muzzle flash. I also managed to test Hell Let Loose which was harder. Each test was done 10 times had 10 shots with outliers resulting in a reset.

My Setup

I have a 5800x3d and a Radeon 7700xt, I used to have a 3080 but it died on me so this is AMD only testing. I’m using an Alienware 1440p 360hz OLED monitor as my main monitor. I tested this on CachyOS, KDE(Wayland) and Hyprland vs Win11. No VSync. KDE and Hyprland are separate installs on different drives both NVME. At some point I will test X11, probably xfce4 and maybe i3.

The Results

Tldr Windows wins, especially with AntiLag but Linux isn’t far behind and could probably beat it with some effort.

Overwatch 2 - 240 FPS In Game Limit(FPS chosen because this is what I can consistently hit in a real game)

Win 11

Avg 19 ms

Max 26 ms

Min 12 ms

Win 11 - Radeon Anti Lag

Avg 15 ms

Max 20 ms

Min 11 ms

Win 11 - Radeon Anti Lag Uncapped FPS / 512 FPS (was facing a wall, not much to render.)

Avg 20ms

Max 28ms

Min 14ms

Linux - CachyOS - KDE

Avg 24 ms

Max 29 ms

Min 20 ms

Linux - CachyOS - KDE - VRR (Wanted to see if VRR made a difference on my setup, it didn't probably because of the monitor running at 360hz.)

Avg 23ms

Max 30ms

Min 19ms

Linux - CachyOS - Hyprland

Avg 24ms

Max 30ms

Min 17ms

Linux - CachyOS - Hyprland - Direct_Scanout=1

Avg 21ms

Max 29ms

Min 16ms

Linux - CachyOS - Hyprland - Direct_Scanout=1 - 360 FPS Limit(Can't consistantly hit this on my setup, results will not apply in a real game)

Avg 19ms

Max 25ms

Min 15ms

Hell Let Loose - Uncapped FPS

Win 11

Avg 30ms

Max 38ms

Min 21ms

Win 11 - Radeon Anti Lag

Avg 26ms

Max 39ms

Min 15ms

Linux - CachyOS - KDE

Avg 36ms

Max 43ms

Min 27ms

As you can see Windows has a slight edge over Linux, on Wayland at least. Direct scanout seems to make hyprland beat KDE a little. If I had to guess the compositor is adding a little latency but Radeon AntiLag also has an impact, there's no reason that can't work on Linux. Nvidia Reflex does I think. I wish I had a comparable Nvidia GPU to test but unfortunately I don't. The performance hit on VK3d for Nvidia might give AMD the edge but I wonder if Reflex working on Linux would allow it to beat Windows in terms of latency.

If anyone has tips for lowering latency on Linux other then trying X11 with no compositor (which I'm going to do at some point) I would love to hear it. Or any critiques of my testing. I know it wasn't totally scientific but I would bet these results are pretty true to life.

Hey guys,

I have friends that play on playstation so when I was on windows, I would use bluestacks to emulate an android phone and use the playstation app on there to have party chat with them. Things to note: I know ps has discord access but it is just more convenient for them to do ps parties and I don't have a ps so I can't use remote play.

I've tried a couple emulators like waydroid and genymotion but the playstation app just doesn't show up on the playstore or it says that it isn't compatible with my device. I've tried to use an apk from APKMirror but waydroid just doesn't seem to want to install it.

Does anyone know an emulator that would work for me? Do I just need to go down the list of phones is genymotion one by one and hope one works?

I have already switched to xe driver btw.

I have already set platform profile to performance.

I am aware I can set in game settings lower.

I am also aware that I could simply buy faster ram.

Plz do not reccomend game specific tweaks (or proton tweaks) as I am looking for universal tweaks.
Like chaning kernel params and mesa settings (if they are even a thing).

I use gentoo btw so my proton prob out performs proton GE binary.

Please give me linux specific tweaks as I find it very annoying to get tips so that are so ovious that I knew back when I used windows.

I installed linux mint and thats when everything went so wrong. i installed steam and all my favourite games but heres the kicker....NONE OF THEM LAUNCHED. i tried using different proton versions and even updating my drivers but nothing worked it would say "launching" and then immediately cancel. since that was a failure i decided to play some good old minecraft but again everything went wrong. it was spitting out lines apon lines of random tech gibberish about opengl and i still dont know how to fix it, so i just played eaglercraft buuuuut it was running at a smooth 10fps. so i decided to switch back to windows but the installer refuses to install saying "Windows could not prepare the computer to boot into the next phase of installation." which nothing ive tried fixed it. so now ive brought out an old laptop and im now copying windows to a usb with wintousb and im gonna clone it to my C drive. thanks for reading even though im probably going to be downvoted into a obvlivion (why is there so much spelling mistakes? because i cant be arsed correcting them)

Hi there!

I have an RX 9070xt Gigabyte OC within and ITX case with quiet fans, running everything at 40% peak. I have been doing this normally with an ambient temp of 28°. The sort of thermal gel on the VRAM was snot effecting reaching out 98° temps for VRAM. As for several reasons my GPU does not have warranty (had to import it, third world is that hard) I dare to replace that with thermal paste.

I put a combination between 1.5mm, 1.0mm, and 1.25mm

In almost all cases, the VRAM was not that hot on idle (between 55° to 60°) but after 20 minutes the best I got was 94°.

After that, I decided to try the last bullet: Chokes, MOSFET and VRAM with 1.25mm. With this one, now the GPU VRAM stays at 90° (8° less compared to stock) but I have the feeling that idle remains higher now (between 65° and 70°).

I was wondering, is it normal? I know I could just push fans further and so, but I like the way fans are rn and also the GPU and CPU temps, including hotspots, are awesome. The only thing I have been struggling with is the VRAM.

I used Thermal Grizzly Minus Pad 8 whenever 1.0mm and 1.5mm, as they do not offer 1.25mm, and then Upsiren 24w 1.25mm for all components in the last one.

Do you think idle being higher now is worse than VRAM being 98° maxed out?

Is that temperature for idle normal or acceptable in the conditions I have my PC?

What are your suggestions within ITX scope?

Best regards!

Really sorry for my lack of knowledge, but I'm new to both modding and Linux. I got a Steam Deck the other day and am wanting to mod Skyrim.

So I followed a guide, and it had me download MO2. I download it, and when I click it to bring up the Zip file, I get a small bouncing yellow square and then nothing. I've restarted the Deck, I've re-downloaded Protontricks. I have no idea what is happening or really even how to trouble shoot it.

Any help is appreciated!

I've been messing around trying to get Elite Dangerous working with the lossless scaling plugin for Steam.

Has anyone made it work? If so, how?

If I try to launch the game in steam, it fails to even get as far as the launcher.
