Screenshot with
GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage showing FPS
drops (DynamicLights=true)
Ok, with the following stack detailed at the end of this comment, the
"DynamicLights=false" case starts to become stable. I am, however, down from
the ~50 FPS during "normal" operations to ~42-45 FPS. The GTT usage stays < 10
MB and the requested GTT size varies between a few hundred K to ~4 MB. VRAM
usage is up to about 950 MB and the requested VRAM is somewhere above 520-530
MB. That said, there are still some drops FPS drops, especially, when you come
around a corner (ie. lots of new stuff to draw). Or you turn really fast. But
after the first turn in the general area the drops are almost gone. The
non-DynamicLights case is now more or less flawless, even if I would expect a
few more FPS again.
The "DynamicLights=True" case is however still a mess. The attached screenshot
was taken with the stack detailed below and DynamicLigts turned on. Again, you
see the ~10 FPS drop compared to the DynamicLights=False case (what is to be
expeceted, considering what Ian said in comment #1, but it still hurts, becuase
~45 FPS is not high enough for a 10 FPS drop to go by unnoticed). And in
addition – even while GTT and VRAM look exactly like the non-DynamicLights case
– you get the constant drops when turning, running, etc.
