Possible GPU bottleneck

post #1 of 9
Thread Starter 
Since I'm in the process of RMA'ing my 460 (just gotta send it in) I've been gaming on my GTS 250. But I think it may be a bottleneck with my CPU it seems. Some games pause for a brief sec then play and framerates can constantly jump up and down but not down to a terribly low point (38fps lowest) and the gaps of the jumping just make it seem worse than it actually is. Is this what is causing this? Is the 250 bottlenecking my 3.8GHz 1055t?

Depends on the resolution, If it's 1080p it's an absolute yes for most games in the past few years.

I think a 250 is a rebranded 9800 Gt ?

My 2.8 quad isn't held back by my 560 Ti, and vice versa. I have an obvious BN in high end dual core games though due to my proc. And I game at 1920x1080.

Could also be a driver issue, reinstall your drivers.

i'm always at 1440x900 even with my GTX 460.

And yes its a rebranded 9800gt+

I've been playing MW2 and Black Ops really with this card lately or L4D. MW2 seems to have a big GPU bottleneck though. I'm also using some pretty dated GTS 250 drivers I think. 260's or something I dont remember.

At 1440x900 there would still be a BN I think, but, nowhere near as extreme as 1080p.

Update your drivers, check "Perform a clean install" too.

Edit - I had a 9600 GT and my current quad and at 1080p in MW2 I maintained between 40-55 FPS most of the time at max settings, 4x AA, 8x Anisotropic. Large areas of smoke quickly obliterated performance though.

I don't ever seem to have a BN with my 460 at 1440x900 but I really dont like that res in general. Its just right in the middle basically. I didn't want to update my drivers but since people here are lazy about going to the post office to ship my card, I guess I'll download the latest GTS 250 drivers anyways.

Im playing MW2 right now and I have it maxed everything. Its running kinda iffy at times. Not as smooth as Black Ops.

That makes sense, I was referring to a 250 BN though.

Good idea.

It happens, I wouldn't worry about it, as long as you're getting acceptable performance. You should also see what your GPU load is when your framerate is at or near what your refresh rate is with Vsync on.

Good idea! I'll open up Precision and check that stuff out now!

Okay Im using all my VRAM and I think thats the problem. Since im used to 1GB on my 460, the 250 only has 512mb.

and about 60%-90% GPU usage with v-sync

Ohhhh, I didn't know the 250 was a 512mb card, that's your problem then sir even at 1440x900 it's surpassing your framebuffer.

Glad the issue's fixed.
