I tried to switch resolution, and i got some results (+3 - 5 fps, nothing substantial) only when going lower than 1280*720. And... quite frankly, the game is a terribile sight to behold on that res.
At 5 hours playtime i was a terrible, terrible player. I failed consistently with every alien lifeform and with every marine weapon.
At 10 hours... no improvement.
At 20 hours... nope, still terrible.
At 30 hours i dropped the ball…
I just tried both tweaks. Disabling paging file didn't help - and switching dll gave me 1-2 fps boost early in a match, while worsening performance in late game.
