Need for Speed.. Hmm..

Well, today I tried to load up NFS: Pro Street, to let my brother play, and everything went fine, the menu was flipping pretty fast around, but the video when you play the campaign went smoothly, no lag, etc. But when I went to race, the game was stuttering from kinda slow to extremely fast, over and over and over again. Odd.


Do any of you know why it's doing this? The only thing I have that's hacked is a d3d9.dll that lets me set any resolution I want. I have it at 2560x1024, for both of my monitors.

PC Specs _______
AMD 6400+ 3.2Ghz
nVidia EVGA 8800GT OC'd
2 Gigs DDR2 (Generic RAM)
Asus M2N-SLI Mobo.

:ps: Win!

I has a fix for it!
If your game's doing this (And with other games if they do the same) - Go into your Option settings, and enable V-Sync.

V-Sync is (From Wiki) Vertical synchronization (v-sync, vbl-sync) refers generally to the synchronization of frame changes with the vertical blanking interval. Since CRTs were nearly the only common video display technology prior to the widespread adoption of LCDs, the frame buffers in computer graphics hardware are designed to match the CRT characteristic of drawing images from the top down a line at a time by replacing the data of the previous frame in the buffer with that of the next frame in a similar fashion. If the frame buffer is updated with a new image while the image is being transmitted to the display, the frame buffer gives it the current mishmash of both frames, producing a page tearing artifact partway down the image.

Vertical synchronization eliminates this by timing frame buffer fills to coincide with the vertical blanking interval, thus ensuring that only whole frames are seen on-screen.

Computer games often allow vertical synchronization as an option, because it delays the image update until the vertical blanking interval. This can cause lowered frame rates due to latency (the period of the refresh rate at maximum), which might be undesirable in games that require fast response (e.g. first person shooters).

VSYNC is also the name of the signal indicating this frame change in analogue RGB component video.

Another thing, if you use a Dual Core (Which I do) some games aren't optimized for Dual Core Processors. They push the game way too fast.
Head to: http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_9706,00.html and download the Optimizer and install it. It worked like a charm for me & NFS:PS.
