gfxreconstruct

Steam Frame comes pre-loaded with the gfxreconstruct Vulkan layer.

To enable when launching the game from Steam:

nano ~/.config/steam/env/gfx.txt

Add the following environment variable settings:

VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_gfxreconstruct
GFXRECON_CAPTURE_FILE=/tmp/gfxrecon_capture.gfxr
GFXRECON_CAPTURE_FILE_FLUSH=1
DXVK_DEBUG=markers

Once you reach the point you want to capture, exit and find your trace(s) in /tmp/gfxrecon*.gfxr

If there are multiple, you probably want the biggest one from that capture.

Don't forget to comment out or remove the lines from gfx.txt when you're done capturing.
