I think I have a different problem from that bug. nvidia-settings says that PowerMizer is set at performance level 2 (maximum performance), even at idle (475MHz/702MHz). Compiz runs nice and fast with both 173.14.12 and 177.80 - it's only when running these games that I notice the big drop in fps.

I have noticed in the past in Hardy that very occasionally frame rates will drop dramatically in games, and I have to stop the game and either restart X or wait some time for it to resolve itself - this might be the card getting stuck at a low performance level like in the bug you mentioned.

I just tried my COD4 benchmark test in a 32-bit version of Hardy, and I got similar frame rates to what I'm seeing in both 32-bit and 64-bit Intrepid. So it seems that in this particular test the 64-bit driver in Hardy gives much better framerates than the 32-bit driver, but this doesn't carry across to Intrepid.
