Summary: Unable to sync to vblank (i810/i915).
Product: Mesa
Version: 6.5
Platform: All
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/i915
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Tested in:
* Xorg 7.1.1 + mesa 6.5.1 + i810 1.7.2
* Xorg 7.1.1 + mesa 6.5.2 + i810 1.7.2
I have noticed a strange behaviour:
- In a light app where more than 60 FPS are achieved, the app syncs to
vblank (getting 60FPS) andthere is not tearing.
- In a heavy app with textures where less than 60 FPS are achieved, setting
vblank_mode=3 doesn't sync withVertRefresh (ie: getting 37FPS) and tearing
appears.
