Hello.
I am using an aspire 5830TG with 6 GB of Ram, Windows 7, Intel Core i5 2450M processor running at 2.50 and 2.50 Ghz. I have an Nvidia GeForce 540M video card with 1 GB of RAM on it.
When trying to play Lockdown as soon as I leave the main base, the graphics take a huge drop in framerates. Everything changes so that all I can see are characters blinking from place to place, and soon I die, and am back in the base. I have tried a few things, but have no idea why this is the case, since the game itself runs perfectly fine.
