Here's what CPU useage I am getting. No idea if Reloaded is multi core or not as yet, hard to say as each core won't be used the same way, as far as I am aware. I'm no expert by any means, but I believe most games split specific tasks between cores, so performance may vary. I don't think you will ever get an equal spread. I could be wrong, I'm going from info I read years ago, so it may well be outdated now.
I have a Q6600, (overclocked by about 400mhz, not that I really see much difference
), a Geforce 260GTX and 8 Gig of ram. CPU usage looks to be on average 30% or so.
I would agree that GPU usage is more of an issue than CPU here, as most games are. Obviously dependant on your system. You would have to have a really slow CPU for that to be seriously limiting your gameplay though.
AI does seem hoggy, however on my setup I have run with a small scene and over 20+ enemies running about. It didn't slow the system that much, certainly less than I expected. I was expecting it to crawl!
Oh, I had Gimp, PSP, Reloaded and Blender running as I normally do when playing with Reloaded, with an obligatory messenger program and Steam of course, plus other basic apps, just to be more accurate.
This probably won't help a blind bit, but I may as well post my screenie too! You never know.
Edit - The original scene was desert, but Reloaded still insists on loading the lush terrain up every time! Even though it says it is Desert. Hopefully fixed next release, if I can help it! Already notified Lee about this.
