That way they are already in memory and load instantly instead of loading them off the hard drive which is much slower.Īny app or game that you run should result in Windows giving that app all the memory it needs. The way Windows prefetching works is that Windows continually gathers data about your usage as you use your PC, and is constantly swapping applications in and out of memory trying to predict (or prefetch) the apps that it thinks you might need, before you even use them. We're talking at least 2.5Gb free memory not being prefetched by other applications. The biggest thing you can do to help SR2 performance is to give it as much RAM as you can. Windows 7 performance is the best, but you'll also need to use the Powertools we released if your CPU frequency isn't exactly 3.2Ghz (the xbox 360 cpu speed.) Vista runs it okay and you won't have to worry about speedup issues. XP will never run the game well because it can't prefetch. These are some minimum requirements to get ~30fps with 1920x1200 and most everything maxed with some dips to maybe 25fps during really fast driving:ģGB RAM with Windows 7 (4GB RAM under Vista) It's not, and I'll get to some ways to fix that lag in after I go over basic hardware requirements. So, you start seeing wild rumors flying around from everyone on what hardware can and can't run it well, as if it's a crapshoot. The prefetching is the thing that tends to throw everyone because it can adversely affect people with optimal hardware that should be able to run the game well. The biggest issue with the PC port of Saints Row 2 is how the engine streams data from the hard drive into memory and how it prefetches (or more correctly, doesn't.) "Is there anything I can do to fix the stuttering and lagging while driving? Make sure Vsync is enabled.įrom Idol Ninja's handy dandy FAQ guide: Power Tools is not needed if you run Windows 8 and is only for Windows 7/Vista if your CPU is not clocked at 3.2ghz. Set Anti-Aliasing Method to Multisampling. Try setting your video cards Texture Filtering Quality to Performance.
