Depends how old the demo code is, but my instinct would be no. There are improvements in the latest beta, notably FXAA adds a good performance boost, but the campaign missions contain a lot of scripting and are heavy on the AI, and thus on your CPU.

Drop a setting or two, maybe on post process, AA or SSAO & you should see a difference. Also experiment with the 'video memory' setting - it won't autodetect and users often report a huge difference when they get the correct vidmem setting.
