I bought Crysis 2 recently for PC at the time I had:
Processor: Intel Core i3 2310M CPU @ 2.10Ghz
Display/Graphics Card: Intel HD Graphics family, total memory: 799MB
Monitor: Generic PnP Monitor 1366 x 768 (32-bit) (60Hz)
OS: Windows 7 Home Premium 32-Bit
Hard Disk: 250GB HDD
The lag made it unplayable (10-20FPS)
I then upgraded to an 120GB SSD, and upgraded the operating system to Windows 7 64-bit Home Premium -- it only reduced GUI lag.
I now have 8GB of RAM, is it worth re-installing (will gaming performance improve)?
