[Bug 252094] Re: Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10
I think the performance regression of intel driver is due to the lost of the 'INTEL_BATCH' variable. This variable can be set in Hardy to get a huge performance boost in 3D (can be seen in glxgears, but also openarena, compizeffects...) for example in Hardy, compare the output of : glxgears and INTEL_BATCH=1 glxgears i have +100% fps on i915 (1024*600 16bpp) : result 1480fps This variable is not set by default on a Hardy install, but it is set when i launch compiz from a console. The problem : this variable is no more used in intel driver (deprecated) so Intrepid can't benefit fom it. From what i understand (being far from an expert ;) ) we have to wait for GEM/TTM to get the same performance in the future... If someone can recompile the intel driver sources used in Hardy, to make it work under intrepid, maybe we can get better results ? see my previous bug on this subject : https://bugs.launchpad.net/bugs/284082 -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 284082] [NEW] INTEL_BATCH=1 not implemented in Intrepid ?
Public bug reported: Binary package hint: xserver-xorg-video-intel The INTEL_BATCH=1 environment variable doesn't seem to work in Intrepid. This option is used by many users to improve 3D performance in compiz, games, etc... on intel chipsets (i915, i945...) For example, without this option, i only get 550fps in glxgears on my eeepc 900A, whereas i can get 1300fps when i enable this option (in hardy) I know there were some remarks about some stability problems with screensavers (see bug #195843) and it was decided that this option won't be set to default. But it think it is very important (if possible) to give users the choice to set it or not, as it really makes a big difference in many applications. thx ! ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- INTEL_BATCH=1 not implemented in Intrepid ? https://bugs.launchpad.net/bugs/284082 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
