Yesterday I overclocked my GTX460 to 775Mhz and the ram to 950 (3800), all on stock voltages, and no problems, but I saw no improvement in Crysis, except when standing still in certain areas; while moving the framerate was pretty much the same.
What is funny is that before overclocking the GPU I had overclocked the CPU from 3.2 to 3.4Ghz and I actually saw a decrease in framerate of about 1 or 2 fps, so I reverted to 3.2Ghz before overclocking the GPU. (could it be because of the uneven 8.5 multiplier ?)
So, could this mean that as is, the Q9550 at 3.2 Ghz is even with the stock GTX460, and I would only see an improvment if I overclocked both at the same time ?
I know an overclock to 775Mhz is not a record setting overclock, but I should be able to see the difference, right ?
Could this be a main memory bottleneck ? I have DDR2 800Mhz running at stock timings 5-5-5-18. Maybe I can only go higher by getting a new computer altogether with DD3 and a new processor family that lower memory access latency.
Or could this be due to the fact that I'm running the 32-bit version of Crysis ? I't s the Steam version, so I don't have an alternative (and yes, I've tried running a patched 64-bit version with some libraries from the internet that I found in the Steam forums, but it didn't work).
Any ideas ?
P.S. I did the GPU overclocking by using Afterburner as I played Crysis, by alt-tabbing between Crysis, fraps and Afterburner, so I could see immediate results without having to restart the game. Is this accurate, or does this give me misleading results ?
