Bioshock Infinite: - the game is CPU-bound most of the time - some small performance enhancements have landed already - the FenceSync optimization is a work in progress, expect a 30% improvement - most of the scratch buffer usage is for private memory, not VGPR spilling (this may be a defect in our indirect indexing) - if I'm not taking private memory usage into account, it's still in top 2 of the worst VGPR spilling apps DiRT Showdown: - the game is GPU-bound - there are a bunch of very slow pixel shaders using while loops, it's unclear how to make them faster - most of the scratch buffer usage is for VGPR spilling - it's in top 2 of the worst VGPR spilling apps</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
