Will the above integrated GPU be able to run RWR?

I still have time to cancel the order and reconsider a different laptop.

the graphic performance relies on the CPU you have into the system. If you have a fast CPU there should be no problem to run RWR imo.
Even though, don't expect to run the most modern games with decent frames. As I said for RWR it should be enough but for more hungry games you might want to buy a "gamer laptop".
What CPU would you have?

Its an undervolted i5 ivy bridge at.. 1.7 ghz.

I dont expect much out of it really. Just rwr, dwarf fortress and project reality.

Hmm hard to tell, try to find some gaming benchmarks with the same CPU to have an idea what games it can run with a fair amount of FPS.
