Description Shawn Starr 2015-09-11 00:42:04 UTC

kernel 4.3.0-rc0 (Fedora snapshot)
mesa git master / with also experimental radeonsi shader cache (still stalls with it even)
LLVM trunk (Sept 10th, 2015 build)

I've done some profiling of Borderlands 2 (just the menu intro) and discovered what may be causing the stalls.

Apitrace: https://drive.google.com/open?id=0Bze7CJKD12nORWQ4RTdIbk4zT1k

Results from profile show the following calls with spikes:

25208614 [glDrawRangeElements]
25208651 [glLinkProgram]
29526799 [glDrawRangeElements]
29526657 [glDrawRangeElements]

The other bug was done. Th

Is this fixed now? I've had the same or a similar problem and it's fixed now. I thought it wasn't fixed for a while until I discovered that limiting the frame rate to 60 is really bad for performance in Borderlands 2...

The stalls were reduced a lot in February 2016, but they didn't disappear completely.

Comment 8 Timothy Arceri 2018-04-03 05:48:44 UTC

radeonsi now has an end-to-end shader cache and glthreading which is enabled by default for Borderlands 2. These issues should now be mostly gone, there is not too much more that can be done. Closing.
