Robot Arena 2 is lagging badly?

[Dangerfield7up]

I am really confused. I have a brand new laptop which easily runs things like Sanctum 2 and Civ 5 with no trouble. Yet on my old laptop, they barely run. On my new laptop Robot Arena 2 runs, but lags badly- Even on low graphics settings!  Yet on my old laptop, it used to run fine! Any ideas to why this is happening or any fixes?

Has your laptop got two graphics cards, like an integrated one and a dedicated high performance one? I had this problem because RA2 was using the integrated card, and I fixed it by setting RA2 to play with the high performance card by default.

I don't know why this could be happening (you could always try a fresh install of RA2) however I do know that the 'graphics' setting actually doesn't really do anything to my knowledge :P
