Who says tiling isn't beneficial though? Maybe on other GPUs tiling might be, it still seems like a radeon centric view to me. I don't think the API should be dictating that, possibly the backend should get more info to decide if it wants to use LINEAR. it would be good if you guys can smoketest this at least, esp if we cc it for stable.
