View Full Version : CPU-limited with P4/2.4GHz?

I get ~48fps in Doom3 (the standard demo). This on a BFG 6800GT OC video board.

My only configuration of the game is to set it to High Quality mode and 1280x1024 resolution. I've done no overclocking of the video card. In short, pretty much everything is stock.

My 3DMark05 scrores are comparable to others with similar hardware (CPU, RAM quantity, video card), yet my Doom3 scores are relatively poor. I keep reading how others with the same video card at the same resolution as mine are getting framerates in the 60s.

My CPU is a Pentium4/2.4GHz, and my system has 1GB of RAM. Is a P4/2.4GHz chip too slow to max-out the 6800GT in Doom3?

Thanks.

I think so. Although it really depends on the detail settings your playing at. Try adjusting the resolution, and if you see a marked difference in the fps.

Sorry to say, but I think you are CPU limited with a 2.4 P4... Doom3 is a very GPU heavy game, but needs a fairly fast CPU to allow the video card to effectively stretch its legs. Have you tried overclocking your processor? I have no idea what you'd be able to get.. maybe 2.7 - 2.8GHz? You could also use a FSB boost. You'd definitely notice the difference then...

Yeah you are deffinitely CPU limited. Especially if thats one with a 400Mhz FSB. Those were much slower than the current P4s (not to mention Athlon XPs or 64s).

You can easily push your P4 2.4Ghz to 2.75Gz with standard cooling, or ever 2.8Ghz if you are lucky.

There was no 400FSB 2.4's, only 533FSB and 800FSB. perhaps you mean that?

Actually, this P4/2.4GHz CPU does run on a 400MHz FSB. Alas.

Thanks for the response.

The 400 and 533mhz FSB P4's are far more abundant. The 800 fsb P4's were introduced pretty recently in comparison.
