Hmm...guessing that's not a good sign these are DXT1 (except maybe High, 3, and 4). I will make backups and try converting them in DXTBMP to DXT1 and report back.

Ok, so looks like converting them all to DXT1 did not give me a performance improvement.

 

Not exactly a solution, but if I keep water at Low.2x performance is fine. There are white flashes, of course, but that may be ultimately a small price to pay.
