This game hates my computer.

I've owned this game for 7 or 8 years now, and I love it. But when 3.0 came out my computer ran it very slowly, so I quit playing and kinda forgot about it. I recently bought a new computer and decided to get back into it, but the 4.0 demo runs just as poorly on my new computer as 3.0 did on my old one. I just cannot figure out why, my pc specs:

HP Pavilion
Windows XP Media Center
AMD Athlon X2 4600
2gigs RAM
nVidia GeForce 7300 LE (256mb)

Any ideas anyone?

My guess is that the problem is your video card's driver. From version 3.0 onwards CM uses a function to draw a triangle a lot to create the 3D ships. If your video card driver is not written well for that function it will run slowly.

My advice is to check if there is a newer driver for your video card and install that if there is.

Another thing that can make a big difference is if you have your screen's colour depth set to 32 bits as older video drivers weren't optimised for that level. Try turning it down to 24 or 16 bits.

I've tried everything I can think of. I just can't get CM to run well on my system. Am I the only one with this issue?

How well do my other games run?

Did you try and get the latest video drivers?

I updated my drivers just a few days ago, with no improvement. :(

Hi crash_sc,

If Sean's guess is right and this is a video hardware/driver issue, you ought to be able to confirm it by disabling hardware acceleration of Windows GDI calls. (In Display Properties -> Settings -> Advanced -> Troubleshoot in WinXP SP2.)

This should fall back to software rendering - not as fast as it could be, but not pathologically bad either.

(Sean - is this just GDI's Polygon() you're talking about?)

Ok, completely disabled hardware acceleration and nothing changed.

I play Firefight religiosly and I've played demos of Sean's other games with no problems at all.

Just curious, are you a fan of Firefly?

Bugger. It didn't seem all that plausible an explanation, but I don't have a better one.

Oh, yes. I'm on the front cover of Firefly Whore Monthly. :D
