Yes, it can be. As of now performance has totally and completely recovered. Most of it was the SDL changes that were so helpful in DRI3 X servers, and a few other optimizations seem to have come down the pike.

[Ubuntu-x-swat] [Bug 1293314] Re: Severe performance regression with xserver 1.15
This bug was finally resolved with updates to sdl, used by all the games I saw it in. When I first changed repos to move to Utopic Unicorn, a new SDL package returned both Critter and Scorched3d to full performance. Then another update reverted some change, and performance fell right back to where it had been. Finally a 3ed update fixed it again, hopefully for good. libsdl1.2debian_1.2.15-8ubuntu2_amd64.deb brought the original fix libsdl1.2debian_1.2.15-9ubuntu1_amd64.deb rolled it back libsdl1.2debian_1.2.15-9ubuntu2_amd64.deb fixed it for good, had this changelog entry: libsdl1.2 (1.2.15-9ubuntu2) utopic; urgency=medium * Restore accidentally-clobbered changes from 1.2.15-8ubuntu2. [ Timo Jyrinki ] * debian/patches/sdl-check-for-SDL_VIDEO_X11_BACKINGSTORE.patch: - Restore old backingstore behavior to prevent tearing (LP: #1280665) Had to revert HUNDREDS of packages one at a time to find this! Any kind of anti-tearing behavior can be resource intensive, I've never had tearing problems in games with r600 but do need to use vsync with video players. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1293314 Title: Severe performance regression with xserver 1.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1293314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1293314] Re: Severe performance regression with xserver 1.15
Updates from 3/17 Xorg benchmarking: On 3-17-2014, I updated X to the latest Trusty packages (xserver-xorg- core=xserver-xorg-core_2%3a1.15.0-1ubuntu7_amd64.deb) and retested. The Critter benchmark may not be of any great importance as it is a 2d game in Opengl that runs very fast, but the regression is on the order of a 49% drop in framerate. This is absolutely repeatable (on two different machines) by leaving only one opponent on the screens and intentionally permitting all shields to be destroyed. The Scorched3d benchmark gave inconsistant results. With the previous X server, I was getting 50-70fps, with the new version I sometimes got 25-35fps, but sometimes got right back to the 50-70fps range, though the highest speeds did not appear as often as with the older version of X. Scorched3d can be a bit difficult to benchmark as which map appears cannot be controlled. In February I got nearly unplayable results in Scorched3d (11-25fps), though some of that was a since-resolved hardware issue and some was the hyper-Z issue with the first versions of Mesa 10.2 installed at that time. No change at all in Critter on Radeon, don't know if these results will translate into regressions on openGL loads I do not have or not. On my Intel Atom netbook, by comparsion, Critter is barely playable due to dropped frames. When the new xserver came out, it was worse, I remember just over 60fps but with worse framedropping than ever. Now about 110 fps on the netbook with fewer dropped frames. My conclusion is that some progress might be being made somewhere, but I don't know what changes in what package are helping if any. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1293314 Title: Severe performance regression with xserver 1.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1293314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1293314] Re: Severe performance regression with xserver 1.15
Further tests with today's Mesa 10.2 (3-17-2014) Getting hard to reliably benchmark Scorched3d due to varying loads, but seemed to run a little faster than earlier test today. Still a bit inconsistant with some screens showing 25-30fps, but more of the screens now at 50-70, and saw 70fps a bit more. Critter was interesting: little change in MAXIMUM framerate, but minimum framerate is now at 75% of maximum,with few drops below 300fps from 360, wich is 83% of minimim. Used to be maximum of 690fps with big drops under load to about (sometimes below) 400fps-all faster than now but much less steady with minumum at 55% or less of maximum. Again, this is not much of a benchmark due to high framerates on a 2d game, but still interesting. It now seems to me that driver work in Mesa for dri3 may be killing this bug one leg at a time. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1293314 Title: Severe performance regression with xserver 1.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1293314/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
