I've started this thread so that we can share some advanced tweak/settings with others, which'll help play ANY games, smoother on low/mid end PC's. the tweaks i've mentioned are for NFS Most Wanted, & were originally suggested by "Koroush Ghazi" from "TweakGuides.com" All CREDITS to him. check out this site for the Tweaks. http://www.tweakguides.com/NFSMW_1.html And for Registry Tweaks go here http://www.tweakguides.com/NFSMW_7.html I did some experiments with the registry tweaks, & found the following settings smoothen the gameplay on low end PC's.(like mine's) Goto this key = "HKEY_LOCAL_MACHINE\SOFTWARE\EA GAMES\Need for Speed Most Wanted", While doing the Registry Tweaks Dont change the Cache size if you have less than or just 512MB RAM, b'coz i tried that & the game crashed. Increase the value only when you have more than 512MB RAM (e.g. if you have 640MB or 768MB RAM, then try increasing that value. NEVER reduce the default value, you can increase but dont reduce. If you have set the Virtual Memory on your PC to more than 500MB (max & min should be set the same), then You can change the SwapSize to something like this--"4194304000" which equals to 500MB or "5033164800" which equals to 600MB. This swap size is nothing but the space set on your HDD by the game to store some (frequently used) DATA. Trust me when i had only 256MB RAM on my PC with Onboard Gfx(P4-3.06GHz; M/B-Intel 915G; gfx- Intel GMA 900), & changing this swap-size really smoothened the game play. I play the game with no problem what so ever in 800*600 resolution, with "Car Reflection Update" set at 1st level, "World Level of Detail" set to 2nd level, Particle System = ON, Road Reflection at 1st level. You can also change the values of Road Reflection, ParticleSystem, OverBight from 0 to 1, That is to turn them ON. (it'll work better on PC's having 512MB or more RAM. Check this pic for the settings= I used TuneUp Utilites 2006 Registy Editor, its really easy to use, & if you do some mistakes, you can UNDO that change in it (just like Ctrl+Z).
