On this note, 8gb of ram has nothing to do with it either. CC is 32 bit so it can only access up to 2 gb of ram. So really, nothing more that 3 gb of ram actually helps things.

I understand that 720 HD is a silly resolution, but I have a 26'' screen, so anything too small is a bit unbearable (although 2x is a nice feature) the problem with running anything lower is that Mouse position registration or acceleration of the cursor is too choppy and doesn't pick up quite as well as 720 HD... Its very very choppy and inconsistent. I tried game pad but while that seems to be the best way to play this game, it just sucks at sharp aiming (I will however try my PS3 controller later to see if that will improve sharp aim)

Y'all are on crack, I can run at 1440x900 w/o lag on my Q9400 @3.2.

What he said. [1280X800 here, can run at 1600X1200 w/o lag, but everything is tooo small.]

I actually could run it with my native resolution without lag, (1680x1050) but, as dragon said, everything gets too small. And it's unfair to play against the AI with such a high resolution.

Have you tried playing fullscreen? That usually cuts down on my mouse choppiness, that or culling the sensitivity temporarily while playing

Fullscreen 640x480 is the only way to play /oldschool cred
No, seriously, it's the best way to play, all the backgrounds are made for this size.

Actually, the new hexcores are also significantly more efficient, not just more numerous.
I play the standard resolution windowed, and with a slightly lower delta time, sometimes switching back for mods where delta time actually effects something. It's probably possible to just modify it so that they adapt to any delta time, but I can't be bothered.

Good news for me then, I am getting a hexcore on ma new comp .

I want a hexcore so bad...

there seems to be some mouse pos and acceleration issues when using a G9 mouse... there is a post about in the support forums...

My biggest lag problems are bombs and when more than 2 or 3 ships are trashed on the map

Then I would consider making the resolution lower, and 26" isn't that big.
Because this is right!(although 720 450 is acceptable as well.16:10)

Any chance that Cortex Command will ever be optimized for multiple cores?

Propably not, it would require so much coding and Data doesn't have time for that.
