Intel's OpenGL Driver Gains Another Performance Optimization
While we have been talking a lot lately about performance optimizations and improvements to Intel's "ANV" Vulkan Linux driver, not all focus has been lost on the i965 Mesa OpenGL driver. In fact, a lot of code landed on Friday for i965.
Enabled on Friday was fast clears for multi-LOD. That came after a number of prep commits and plumbing to the i965 driver.
The end result? A minor but noticeable improvement for relevant OpenGL test cases.

On SKL (also fast clear is used for level 0, layer 0): Manhattan 3.0: 3.88434% +/- 0.814659% Manhattan 3.0 off: 3.25542% +/- 0.101149% Trex: 3.43501% +/- 0.31223% Trex off: 4.13781% +/- 0.0993569% ON BDW: Manhattan 3.0: 1.37079% +/- 0.571208% Manhattan 3.0 off: 1.74029% +/- 0.267499%
