Have you guys considered including RTS titles like Starcraft 2 or Dawn of War? Some of the custom maps on SC2 particularly will really strain a PC
We used to test Dawn of War 2, but AMD's drivers cheat in that game by only drawing 24-bit instead of 32-bit colour, so AMD cards had an unfair advantage.
apart from looking a little better the biggest thing i noticed was the AI's behavior, they used to leap about like ninjas which was completly at odds with control interface as you could never keep up resulting in people sprinting everywhere and burning out the suit. now they're more cautious and slower to engage, they're still lethal when they score a hit but now they play more in line with your cumbersome movement, silencers now dont alert the ****ing world and deflection is no longer broken and actually deflects enemy fire properly. oh and they're slowed you down a bit as well. feels more tactical now and as a result you're more inclined to try the other weapon attachements. **** i ran it lastnight with all suit modules turned off it felt so good.
