You can use the GALLIUM_HUD environment variable to find out the cause
of those hiccups. Just set it before running steam. Type
"GALLIUM_HUD=help glxgears" - that should print the available options.
From the top of my head, the useful graphs are:
- num-evictions (TTM overhead as the number of buffers moved)
- num-bytes-moved (TTM overhead as the number of bytes moved)
- num-compilations (compiler invocations)
There are also a bunch of useful things like various VRAM and GTT
usage stats, GPU-load, etc.
