[Fud] ATI physics to stick to CPU - Page 2

post #11 of 36
I would much rather use the extra CPU power that just idles when playing games, rather than using GPU power (that I use %100 of normally) for physics....maybe that will change in the future, but it seems premature for GPU acceleration now.

Nothing I have said suggests that. I know GPU's have far more processing potential in the Physics world than CPU. I am just saying that for now and the near future that CPU's should cope just fine.

They should make the games efficiently use more than 1 of the 4 available CPU cores. The GPU might be able to process the work but it has enough to do.

Yeah I agree. I really wish some games would REALLY utilize more of those cores. They really dont take advantage of them at all. Not even close. I thought Crysis was going to set the standard when it came to Quad core usage but I found it never did.

The point is.....

GPU's parallel processing is inherently better suited than CPU's serial processing for physics.

i.e. 10,000 pieces of debris from a single explosion. The GPU is better suited for these types of calculations.

Indeed Duckie. The GPU's are much better suited to that kind of task. I am not saying its not to those who think I am. I am just stating that ATI probably made the right move in sticking with CPU physics for now.

I'm not sure if this is related to the topic but here is my 2 cents. I recently activated the physics ability of my 8800GT. Sense then I have not noticed any of my games shudder and seem laggy in certain situation. A good example is like in the game GRID... when I slide into the dirt initially when I got the game it would have a brief half second lag while the dirt kicked up. Now it seems much smoother and fluid then this happens. I actually had better control because that half second of lag always made me over steer and spin out. My driving actually improved and thats no joke. Another example, when the Titan blows in BF2142, when the Titans first appears blowing up. I would get that split second of lag right at the first initial explosion. Sense enabling the physics of the card I have not notice that happening. Like I said, it may not have anything to do with the topic at hand but I honestly think that it made a difference.

Just a thought though.... BF2142 is maxed out as far as setting go. I mean MAXED right the hell out using nHancer utility to override the game setting and NV control panel settings. My 8800GT runs it smooth smooth smooth (minus that one little part I mentioned). So if in fact the physics did load onto the GPU I doubt that it made any more of a load on the GPU. On the other hand a game that is DX10 I'm sure would have a much profound and noticeable impact on the GPU ability to keep up.

I personally think current hardware is perfectly fine for at least the couple years, the problem is that the workload just isn't spread out evenly, even dual core's arent being completely used in games. If they were able to optimize games so that every single component was being used at a 100%, we wouldn't be discussing this.

But I guess making games used multiple cores is just so much more difficult then unloading physics to the GPU.
