[Bug 901097] Re: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.
Care must be taken with removing glFinish as doing so may cause additional latency. Ideally the drawing should occur as late as possible, right before the buffer swap (1-5 ms latency at compositing stage) but it may be difficult to guarantee that the deadline isn't missed (causing frameskips). Drawing right after the previous swap is much easier and still acceptable (one frame latency). If no glFinish is done, the display driver may buffer multiple completed frames, leading to high latency. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/901097 Title: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.

[Bug 901097] Re: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.
But don't panic too much. Before new rendering modes are added, I planned on adding a simple config option to the opengl plugin so we can switch between the existing (and future) rendering modes. So we don't need to settle on a single solution. Just decide which is default :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/901097 Title: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.

[Bug 901097] Re: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.
Even 400 lines is way too much change for precise. And I haven't done any performance testing on it yet. At the moment forcing full screen redraws provides the highest framerates and lowest CPU (compiz+Xorg). It also means regional damage debugging with showrepaint is irrelevant. And it's even lower CPU than the prototype in comment #1. Keep in mind that the opengl plugin goes through the motions of drawing ALL windows regardless of the rendering mode. So the more complex the regions (even if they're small), the more CPU it uses. I would like to benchmark the GLES rendering when I have time. But it's irrelevant this close to release. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/901097 Title: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.

Sam, I reviewed the options again last Friday. What I found was: 1. The GLES branch looks promising and merges cleanly but: (a) It's too late to consider a new core rendering algorithm for precise; and (b) The diff is still over 11k lines. Yet another reason why it won't land in 0.9.7. 2. Forcing full screen redraws (not really a code change, just a config change) now performs better than regional redraws in most cases. Full screen redraws provide higher framerates and equal or _lower_ CPU usage than regional redraws. The only exception was on a very slow system which got its framerate doubled, so the CPU increased somewhat in a good way. The other problem with full screen redraws is that there seems to be high lag when used on multiple monitors. I think someone has logged a bug for that already... I personally would not mind forcing full screen redraws right now as it will fix more peoples bugs than it would cause. But I won't do so because we are in freeze and it would still be risky to change core config so late. 3. Interestingly in the GLES code I saw some hints that they encountered the same kind of rendering bugs as I did with my prototype in comment #1. This suggests they are indeed plugin bugs. I think at this late stage in the precise cycle, then only sane solution to bug 930192 is not to fix this bug yet, but use one of the quick solutions documented there --> bug 930192. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/901097 Title: Add option to use glXSwapBuffers on every frame, not just full-screen redraws.
