Boot camp dual core question.

I'm having this weird issue while playing Left 4 Dead. When I set my shader on high (max res) the game freezes here and there for a few second (sometime from 6-13). That happens when I just launch L4D by itself. If I run something else, let's say Firefox and the game the freeze occurs less. So when I have another game client running (not a game, but something like steam, but more cpu intensive) L4D runs smoothly under high shader, no freezes once so ever. So basically if I have to have applications running before the CPU kicks in it seems like.

So to confirm this is there a tool in xp that monitor dual core cpu usage? If that is the case (where I have to run multiple things) how would I fix this? Has this happen to anyone before?

I'm running XP pro 32bit too, does that have anything to do with it? I just think that 3gb is plenty of ram under windows since all I do is play one game.

Edit: Could this be a Ram issue instead of CPU? I checked w/ core temp that when the game is running the CPU is like 90% used on each core.

Thanks.

 

Do you have SP2 installed?

cheers ...

 

Something is off with the bootcamp drivers I reckon.

My CPU is reported incorrectly by GTA IV. It says I have a Xeon III processor, when I have the c2d 2.53....

Wonder if it's a driver issue..

 

Does CPU-Z correctly identify it?

 

I haven't tried that, but Windows identifies it correctly.

So that points more towards GTA IV not identifying my CPU correctly..
