About this mod
Vulkan wrapper, hotfixes and engine tweaks for a stutter free experience. READ DESCRIPTION.
- Permissions and credits
- Changelogs
TESTED WITH nVIDIA cards. AMD support is hit and miss.
Using Vulkan DXVK Async the game FINALLY gets rid from the stutters when loading textures.
NOTE: DLSS, NVIDIA LOW LATENCY AND RAY TRACING IS DISABLED.
To enable HDR open dxvk.conf and uncomment (remove #) "# dxgi.enableHDR = True" to activate the setting.
This is a pack containing:
Edits in Engine.ini from various sources, mainly reddit posts.
DXVK 2.1 Async fork from: https://gitlab.com/Ph42oN/dxvk-gplasync/
VKD3D from: https://github.com/HansKristian-Work/vkd3d-proton
INSTALLATION
- From folder WindowsNoEditor, copy Engine.ini in %AppData%\Local\Hogwarts Legacy\Saved\Config\WindowsNoEditor OR use your preffered engine.ini
NOTE: If using your own engine.ini, MAKE SURE to add r.AllowPointLightCubemapShadows=0 (Needed to avoid DXVK crash with Lumos at certain scenarios.)
IMPORTANT: if using the mod engine.ini : edit r.Streaming.PoolSize=3072 to match your specs. Use 2048 for 6GB vram, use 3072 for 8GB vram, use 4096 for 12GB vram.
- From folder Win64, copy d3d12.dll, dxgi.dll, dxvk.conf and dxvk_config.dll in: \Hogwarts Legacy\Phoenix\Binaries\Win64 (Game exe dir)
- Delete everything in %ProgramData%\Hogwarts Legacy (IMPORTANT)
- Start game and wait for the shaders to compile. After the first compile exit the game and start it again.
Enjoy a stutter free experience - at last.
About FPS: If you are on a slightly older CPU, this will improve your FPS. If your CPU is new(ish), the FPS may be less than with DX12 but the stutter situation will be improved. Test and decide for yourself.
KNOWN ISSUES:
- AMD support is not at a good level. Does not work with the newest RX6xxx series, RX570, RX5700 and others. Your mileage may vary.
- If the game crashes at launch, make sure to NOT press any key or move the mouse before the screen "Press any key" appears. This usually resolves the issue.
UNINSTALLATION:
Delete all the files added by the mod to revert to DX12, and delete everything in %ProgramData%\Hogwarts Legacy .
