Yesterday, I updated to 11.11a and noticed a nice improvement in performance. Nothing ground breaking but enough to see that the perf overlay chart ms results was a little lower and with less spikes. Frame rates improved at 1080 resolution and was more flat when there was a lot of explosions going on in a 64 player server. As of today, after the update, my frame rates are a lot lower then it was before. The perf ovelay chart is spiking all over the place. After trying a few servers (both 32 and 64 player) nothing I have done so far changes this. I also found a threads here: http://forums.electronicarts.co.uk/battlefield-3-pc/1456369-lost-10fps-after-patch.html http://forums.electronicarts.co.uk/battlefield-3/1456726-fps-drops-after-latest-patch.html discussing the issue and that person isn't using a AMD card. I have to wonder if we need a new driver. I don't know...call it 11.11b or something because 11.11a was working great for me yesterday before the patch. Note: I rarely create threads like this as I usually don't have problems. But when I do I know I'm not the only one.
