the game uses a shocking 112 MB of VRAM @1080p lol... and there's no .ini file or anything to bump that value like we could in Bioshock, seriously the GPU clock throttles down to 300 MHz and memory to 150 MHz same as I was reading some text document... so seems like the CPU does all the job here.. there's no excuse this game won't run on integrated GPU's, lazy port. Hitching/stuttering look hard-coded, a "feature" from the 360 version code, don't think we will see that fixed.
