Enable hardware-accelerated GPU scheduling (I had turned this off because it caused issues in another game, I can't remember which one). Windows search for "GPU" to find this setting, a restart is required.

Navigate to "AppData\Local\Hogwarts Legacy\Saved\Config\WindowsNoEditor" and backup "Engine.ini". Add the following to the bottom of the file and save it:

[SystemSettings]

r.bForceCPUAccessToGPUSkinVerts=True

r.GTSyncType=1

r.OneFrameThreadLag=1

r.FinishCurrentFrame=0

r.TextureStreaming=1

r.Streaming.PoolSize=3072

r.Streaming.LimitPoolSizeToVRAM=1


[ConsoleVariables]

AllowAsyncRenderThreadUpdates=1

AllowAsyncRenderThreadUpdatesDuringGamethreadUpdates=1

AllowAsyncRenderThreadUpdatesEditor=1

3. This only applies to Nvidia users, set the shader cache size to 10GB in Nvidia control panel global 3D settings.
