Tech Advice on Running GWX 2.0

[astroglobe]

Hey folks

Wondering if you might have some advice on running GWX 2.0 on my system.

I have a Dell Dimension 4600 with Pentium r4 CPU with 2.4 GHz, 1.50 GB memory (of which 63.3 GB is free) and an Nvidia GeForce 6200 card. It works pretty well for the most part but it can start to lag when some of the action gets heavy (especially with big fleet action combined with air attack).

Any suggestions on how I might tweak my system to speed things up and run GWX 2.0 at optimum - or do I need to bite the bullet and upgrade to a new machine? (ps I've also got SH4 which barely works on my system).

Any suggestions would be most appreciated.....
