Specs

GPU: NVIDIA 1660Ti
Drivers: 495.44

Using latest Proton-Experimental as of posting this.
Using vkd3d-proton built from master (commit: https://github.com/HansKristian-Work/vkd3d-proton/commit/99e067d6816c07b773b6856ba0ec5e7257bc41c1)

Description

Hellblade: Senua's Sacrifice recently had an update on PC where they added support for AMD FSR.

Enabling FSR on vkd3d-proton results in the game freezing with the following console spam :
0154:fixme:shader_sm4_read_param: Skipping modifier 0x00004000

Setting VKD3D_SHADER_DEBUG=none works around it and FSR works as expected.

Reproduction steps

Turn on AMD FSR in the graphics settings on the latest update.

Edit

To be noted is that the game doesn't really freeze indefinitely. It only freezes/waits, while spamming the console with fixmes, for around 30 seconds before continuing normally as expected.

This freezing/waiting is reduced to 0 seconds when setting the above VKD3D_SHADER_DEBUG to none.

Please let me know what else would be helpful. :)

Does it really freeze or is it just taking its time spamming log messages?

Enabling log messages does not magically create an infinite loop out of nowhere, it's just slow, and we should probably ignore some of the modifiers.

That makes sense yeah.

My bad, looks like you're right. I didn't let it run long enough as soon as it froze. It exits the freeze and continues just as expected after waiting around 30 seconds.

I'll update the issue to reflect this more clearly. :)

Feel free to close this issue since https://github.com/ValveSoftware/Proton/pull/5326 has been merged in proton experimental - which fixes the short freeze.
