Worryingly lower FPS than expected in Supreme Commander.

Recently bought a new rig:

Asus P5Q Pro P45
4Gb RAM
Vista Premium 64bit
ATI HD 4870
Intel q6600 @ 2.4ghz


Im getting around 25 FPS in a skirmish in Supreme Commander. Generally dips to a low of about 10. Having based my choice of system, to a degree on the reviews of this site, (See http://www.tomshardware.co.uk/rade [...] 6-11.html) Any one have any idea as to why such low FPS?

My ATI drivers are up to date, as it Vista.

Admitadely there are 4 AIs, on an 80x80 map. Still, early on into the skirmish I was expecting a better framerate.

Again, some help with this issue would be much appreciated.

True; but this was run off of the SupCom official benchmark, built into the game. http://www.techarp.com/showarticle.aspx?artno=493 that was the guide i was basing my resutls off of.

Generally my avg FPS comapred to there cards and processors, is roughly half, somthing that surprises me given my system spec.

No, nothings wrong with your system or video card, it's your CPU were the bottleneck is. I play Supreme Commander Forged Alliance and the AI spams loads of tech 1 and 2 units. I have a E6400 @ 3.04Ghz and I played against 2 A.I opponents and after about half an hour the game slowed down as the the AI just sent countless tanks and bots to my base.

Each of those units has an A.I tree that it follows and what path is chooses is formulated by some complicated mathematical formulae, give the amount of work the CPU has to do it's no wonder your Computer buckles under the strain.

In future limit the maximum number of units each side can have.

im not sure what my exact fps are but it never chops or lags at all on my setup @ 3.8. you guys need to bump up your clock speeds and it will all be fixed man - this is also on the biggest map with all AI's and max unit caps.
