Well, don't get too happy yet. I only replaced one heuristic with some other one. It's possible it will behave worse in some other app, who knows. Buffer placements are not a solved problem yet. We need a solution that is more robust in extreme scenarios.

Somebody should try benchmarking the patch with an R600 GPU that has very little VRAM.
Do all the open source graphics drivers have these buffer heuristics problems?Last edited by Sidicas; 01 November 2012, 10:30 AM.

However it is not this patch as I am already few commits back with checking and it is still there

So it's just trading apples for oranges, although it certainly seems better to assume that the user has bought enough VRAM to play the games they're trying to play, it's certainly possible some users with cheaper hardware are better off without this patch, right?.
