Info: Why is Need For Speed: Most Wanted so choppy even with 1 GB+ of RAM?

post #1 of 9
Thread Starter 
So, noticing a bit of choppy game play in NFS: MW, even when you have 1GB or more (this tweak will work even if you have less) of RAM? Wondered why? Well, in short, it is because Need For Speed: Most Wanted is only set to use around 350MB of RAM. This can be changed though, to use whatever value you want.

To edit the amout of RAM used, to into the registry. To do that, go to start, run, and type regedit and press enter. In there, look for:


[HKEY_LOCAL_MACHINE\\SOFTWARE\\EA GAMES\\Need for Speed Most Wanted\\]


Once there, take a look for "CacheSize". This determines how much RAM is being used. Like I stated earlier, it usualy is around 350MB. The value in the box will be something like "2969567232", which is in bits. That number is what is used on my computer for the game. That translates to 354MB.

If you want to see what your value translates to, divide the number if what it says in the value, divide that number by 8388608. You do this because since we all (should) know, that since 8 bits is equal to 1 byte, and 1024 bytes = 1KB, and 1024KB = 1MB. Or, in other words, 8x1024x1024. I set this value to use 850MB of RAM (7130316800 bits) since I have 1GB. I suggest using the following depending on the amout of RAM you have.

512MB -> Default
768MB -> 550MB
1024MB -> 850MB
1.5GB -> 1GB
2GB -> 1.2GB

The reason why I don't suggest much more from 1.5GB to 2GB is because the game probably won't utilize that much RAM anyway, and you have you keep in mind you have to still leave some RAM for the programs in the background too.

Have fun. Easy mod to do, and I noticed very little, if any choppyness after this.

Great FAQ! Since I started playing NFSMW I have been searching for a way to stop the glitching. But, even after changing the cache size to 850mb like you suggested, alt-tabbing out of the game and going into task manager shows that it is still only using around 380mb and I still had the glitching in the game?

Thats because its only using 380MB- when it needs more it'll use more. So when you alt-tabed out, it only needed 380MB.

Never had that problem. Probably wouldn't hurt to try. I'm sure it will- unless your sure its not a graphics problem.

Will this work with most PC games, uping the Cache?

Depends mostly on the game. Most game puts a much larger amount than it would really need, but NFS:MW does the oppisite.
