Warsow 1.0 at 1920 x 1080 was running just shy of 30 FPS with the i5-3470 and slightly behind the i5-2500K. The Intel Core i7 3770K remains the major frontrunner.
Xonotic with low quality settings at 1920 x 1080 was running at the same speed as the HD 3000 Sandy Bridge graphics.
When Xonotic was bumped to high quality settings the frame-rates quickly fell off and the i5-2500K with double the execution units of the HD 2500 graphics was running stronger.
Running Xonotic at 1920 x 1080 with ultra quality settings led this open-source first person shooter to running at sub-30 FPS.
