Im using a Dell XPS 15 (L501X), has Intel Core i5 2.53 GHz, 4GB RAM, windows 7 64-bit and Nvidia 420M GPU...
basically when im not playing a game or doing a graphics intensive acitivity, the GPU shuts down to conserve power, and the integrated graphics chipset kicks in...as soon as I turn on some graphics intensive application like starcraft 2, the GPU becomes active
the problem is that in the case of RA3 Uprising, that doesnt happen and it tries to run the game on the integrated graphics instead of the GPU. Also when i look at the GPU activity meter, it doenot show any GPU usage which confirms this....ive tried a few workarounds on the internet but they dont seem to work
