HelixSR has been released in version 3.3.0.

The tool brings DLSS upscaling and frame generation to non-NVIDIA graphics cards through a single DLL.

HLX FSR 4 Full now supports more AMD GPUs (including some RDNA 1, 2 and 3 cards and the Steam Deck), and HLX DLSS runs natively in Vulkan games instead of through the DirectX 12 bridge. The installer now builds the Vulkan kernels opt-in only. According to the developer, the release was only tested on an AMD BC-250 under Linux.

HelixSR 3.3.0

• Installer: HLX DLSS Vulkan kernels are no longer built by default. Opt in with --vulkan (Linux) or -Vulkan (Windows). Preset K now builds on Windows as well.
• HLX FSR 4 Full: support for more AMD GPUs, including some RDNA 1, 2 and 3 cards and the Steam Deck. Speed gains on several NVIDIA, AMD and Intel GPUs.
• HLX DLSS: runs natively in Vulkan games instead of through the DirectX 12 bridge. The bridge still applies when the Vulkan kernels are not built.
• Preset K: all layers run as DirectX 12 shaders on Windows. New Int8 setting in helixsr.ini controls 8-bit math use.
• NVIDIA GTX 10 and 16: use faster 32-bit paths on Windows and Linux.
• HelixSR Scaler 2.3.0 is bundled and lists HLX FSR 4 as an upscaler in Vulkan games.

Known issues: A game may freeze at startup with Preset K when the Steam overlay is enabled (disable the overlay for that game). Preset K with DeepReuse 1:2 or 1:4 caused one GPU hang on a BC-250 at 1440p; the default Exact is the safe choice. HLX FSR 4 Full with 1:2 or 1:4 shows some ghosting in motion. Preset K can sparkle on foliage at any DeepReuse setting.

Only tested on an AMD BC-250 under Linux. Windows, RX 6000/7000, Steam Deck and NVIDIA GTX were not tested; logs and speed test results are welcome.
