Ahoey,
I' gonna take this opportunity to give some advice to those who use a weak computer with PES2010, since I'm using a fairly old laptop and have an almost perfect experience, with no issues related to response time, framerate drops, or game speed:
My rig: MSI GX600 Laptop with Intel 2C 2.1 Ghz, 3Gb ram; video Nvidia 8600M gt (512GB DDR2), XBox 360 Controller.
System: Windows XP Pro SP3, Nvidia driver 178.24 (get from laptovideo2go.com, it't good for the rpg "Risen", works perfectly with PES, in spite of its age)
System settings - virtual memory disabled (to eliminate lag due to hdd swapping), Nvidia drivers - default settings, only enabled triple buffering for PES (no modification to render ahead frames, quality settings, nothing); !Defragment the partition where PES is installed, you will get rid of the lag when the game reads audio files during the game
Game Settings:
- i'm using a resolution of 1280x768, "lb" unticked, 16:9 (my native res is 1280x800, with these settings I get 2 black bands od about 4 mm, unnoticeable really)
- high quality, use frame skip, vsync enabled - those are a must to eliminate tearing and framerate drops
-kitserver installed, only enabled dll = afsio.dll dll = afs2fs.dll via config.txt (use it for chants, ball cursor, league logos)
With the above the game is very fluid, I'm enjoying it with absolutely no issues. I get some slowdowns during replays but in-game it's buttery smooth and perfectly responsive. My guess is that using Windows Xp would be the first thing for people with issues, Vista is a resource hog and 7 is not mature enough (and a resource piglet, too).
Hope this helps.
