I installed 32-bit linux because back in the day 64-bit linux missed out on some cool stuff like java and flash. Some of those things have been resolved (maybe all, I'm not as up-to-date as I was) and currently I'm having performance issues with the 32-bit versions of the ATI binary driver. The machine I'm on is 64-bit wide so I could switch to 64-bit, but I'd like to do so only if there is an advantage to it.
Are 64-bit ATI binary drivers better/faster than their 32-bit counterparts?
With the shift to 64-bit a lot of things change at the instruction and hardware levels. I would expect 64-bit drivers to be able to process more data in a shorter amount of time. I don't know if the types of operations that GPUs benefit in this way or not. My feeling is yes, but by how much I don't know. So I'd like to know if anyone has spec'd a GPU (specifically an ATI one, since that's what I have) using 32-bit and 64-bit drivers and seen a vast increase in speed on the 64-bit one.
