It's really weird, back when I had a 1200x720 box monitor (hard times

) a few months ago, I couldn't get anything on GTA IV.
1200x720 resolution
1024MB DDR5 HD Radeon 6850
8GB DDR3 RAM @ 1100mhz
AMD Bulldozer 3.6ghz x4
Everything was literally on medium, I think even a few things were on low, I had about 400/1024MB resources used and saw with Dxtory that I was getting a semi-stable 20fps, with occasional spikes that dropped it into the low teens.
What the hell was wrong with Rockstar back then? At least Max Payne is alright, but there is no real way to tell, as it may be on the same engine more or less but the graphics are barely any better. Grand Theft Auto 5 looks stunning, and will probably be even more demanding and on its period than 4 was.
Rockstar need to sort themselves out to be quite honest.
