The problem also exists on nexuiz. The problem doesn't exist on IVB. Ian, can you reproduce it? Works fine for me... The problem still exists below environment: -------------------------------------------- Libdrm: (master)libdrm-2.4.43-5-gb7bb9e929786eb8bae86cf50f54dcb94bfa7ad46 Mesa: (master)cb12bf7606116e473bf19aee84582b4cee7f895d Xserver:(master)xorg-server-1.14.0-52-gecf62755086fd65898998d5a509aee5f29a9583d Xf86_video_intel:(master)2.21.6-9-gafe61281d8f92d6eb841e2522ab18e0d2fe73773 Cairo:(master)a64ce09715162c57d6e4b6a460d426af1d443cdc Libva:(staging)5ec25c3d563d9ebd479a5ff978afe0a32f9cc00b Libva_intel_driver:(staging)1fd62ffd336293dce7d091bcea8399a40ccea21e Kernel: (drm-intel-nightly) 524d90c616e56dcd9b64432a68f6013bd1e82811 OS ---------------- Fedora 16/17 gnome-session or X raw Hardware: --------------------------- Piketon# Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 12) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) Calpella# Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) Games ---------------- doom3 v1.3.1, nexuiz v2.5.2, openarena v0.8.8 Ian, comments? Ken already said he can't reproduce it. We've had no other reports of performance problems in openarena on any platform. Just compared bad and good build when running openarena
Seems the difference is:
Good build, CopyTexSubImage2D seems to hit fast path
Bad build, CopyTexSubImage2D seems to hit slow path (_mesa_meta_CopyTexSubImage)
openarena only uses glCTSI on some graphics settings, which would explain why we didn't see it. Patch is on the list now. And pushed: commit 4dea6cf21557bcd3bbab3402e19e19f665d7e177 Author: Eric Anholt <eric@anholt.net> Date: Tue May 28 10:59:53 2013 -0700 intel: Enable blit glCopyTexSubImage/glBlitFramebuffer with sRGB.
