Comment # 13
on bug 84627
from smoki
Maybe to mention here what i playing a little there yesterday, it is not only
PIPE_USAGE_STREAM reverted which triggers problem/corruption on 32bit, for
example if i only add res->domains = RADEON_DOMAIN_GTT; to default i can't
login anymore:
default:
/* Not listing GTT here improves performance in some apps. */
res->domains = RADEON_DOMAIN_VRAM;
+ res->domains = RADEON_DOMAIN_GTT;
flags |= RADEON_FLAG_GTT_WC;
break;
On 64bit this is also not a problem, after adding just this performance goes
up by 25% in games like Torchlight, Dota2, etc... i only found slight decrease
in other apps by up to 1-3% (Xonotic, Openarena, etc) and it also remove
stutter for me in Unigine Valley. So this seems to be better default now,
but...
Then again that is only because 'flags |= RADEON_FLAG_GTT_WC;' is there so
that made a difference to not fps go down much. If commented that (with
DOMAIN_GTT there) a see even greater boost by 35%-40% performance go up in
Torchlight, but it is not actually so good anymore for other apps (Valley
suffer). So that seems like some apps very much like, but some not at all :D
Yeah on 32bit i can't play with those, there are various triggered problems
with GTT_WC being there.
