whats nvidia physX? and can i get it on my 8400m gs? i saw the Aegia PhyX card but dont know what it does, hell it even has the same amount of memory as my graphics card! :O

PhysX was a technology to accelerate physics processing in games (moving objects, water etc), developed by Ageia. It had a poor uptake due to lack of game support and cost of the PPU (Physics Processing Unit).

Nvidia recently acquired Ageia, and implemented PhysX into their graphics cards. This uses a technology know as CUDA, which is available on all (I think) 8 series cards and later, so you should be able to support it. It works by moving physics calculations from the CPU to the much more powerful GPU, which should speed the game up when you have spare graphics grunt available in a physics heavy game. The game needs to be PhysX enabled.

I don't think it would work too well on an 8400M, as it doesn't have a lot of power. Also, I don't think the necessary drivers are available for the mobile GPUs yet.

BTW, the reason they haven't tried doing everything on the GPU is because CPU architecture is much more flexible, so will do lots of things faster than the GPU, just physics is very similar in nature to graphics.

PhysX will not work on your chip, as it is for 8800 and above only.

Ohhh, I thought it was all 8 series, lol.

aww man i not bothered though i still set physics quality in crysis to very high

Crysis uses its own physics engine, different from Havok and PhysX that just takes advantage of multiple cores on a CPU, kind of like HavokFX.

so what kind of games dont you need a physics accelerator for the physics? i know half life 2 and crysis dont need them now

Only the games that are specifically branded for Havok and PhysX will use enhanced hardware physics acceleration. Games like GRAW2 and UT3 are branded for PhysX and you'll see this on the box cover.

oh yeah i installed ut3 demo i had to install some physics software in it, and in the menu it says enable hardware acceleration, can i tick that? ( i have 8400m gs

You can try it but I think it will slow down the game quite a lot!

what will it add to my game exactly because i dont kn ow the difference

Hardware physics should mean you get more physics objects and the like, but with an 8400M you would be doing it at the cost of graphics performance.

so i should disable it?

I don't think you'd see much benefit from it, and I'm not even sure you comp can actually use it.

wtf eve online 544 hours?! thats insane?! think of all the noobs you meet

Kinda random, lol. I have been playing it on and off for over a year though.

how do i put my steam stats into my signature?

Those are xfire stats -> www.xfire.com

i have xfire too how do i put them in?
