*** Bug 323818 has been marked as a duplicate of this bug. *** This has nothing to do with the GL version (if actually reset that's either due to HW support or a different bug) but a problem to reliably detect the availability of triple buffering. see dupe. *** This bug has been marked as a duplicate of bug 322060 *** well, what i dont get then why do i have a performance and a tearing difference? no tearing if i reset the opengl option, but the tearing is present again when i reboot. (In reply to comment #3) > well, what i dont get then why do i have a performance and a tearing > difference? Did you read across the dupe? In a nutshell: triple buffering is (likely) misdetected during login. Without either it or usleep yielding, swapping causes high cpu load, so it's forcefully deactivated. W/o triple buffering, also chances raise to drop or miss a frame (because we stay in event processing as long as possible) and the event processing time naturally shortens as well -> seems slower. -> Ensure to activate triple buffering and override the detection. |
