FWIW, Timo Aaltonen just noticed that Warsow performance went down by around 80% with commit 61e264f4fcdba3623781a0a339426672f0d431e4 (mesa: Prefer non-swizzled formats for most sized internalformats). Apparently, we fall off the BLORP path now. However, this patch series improves Meta's CopyTexSubImage to the point where performance is back to normal. Convenient timing :) Feel free to commit this. --Ken
