The commit itself is fine, it improves performance in *many* tests significantly, to what their performance should have been. We'll still want to know why only this test [1] was affected by caching mode setting, so bug can be kept open. However, GL_POINTS is less important test and its performance is currently good enough, so setting bug importance to lower. [1] Were any other tests affected negatively (>10%)?

According to our test results , only for this case its performance is down 25%. The others are positively affected. This bug is also exist on Mesa10.4RC1 |
