CPU bottlenecking GFX card

post #1 of 16
Thread Starter 
Hey guys I just had a pretty easy question. I recently upgraded to a Radeon R9 280x and it's a SUPER nice card. I got it to play BF3 and BF4, which it does pretty good at high and ultra settings. When I first got it I never noticed any kind of slow downs, but now after a couple of weeks I'm starting to notice especially on larger servers that sometimes I lose FPS for no apparent reason and I can't figure out why. I have an Intel Core-i5 2300, which is a 2.8ghz quad. I'm thinking that when I first got the card I just didn't notice the smaller details. Is it possible something has gone wrong with the card to cause this? Or is my CPU bottlenecking this GPU?

That issue gets solved by using windows 8.1 and using mantle(also unparking cores)

I just looked up a tutorial on core parking and went to the resource manager like it says to. None of my cores are showing up as parked at any time so I'm kind of doubting the efficacy of unparking them when they are already not parked as is. Also I don't think BF3 has Mantle support.

I usually don't go for any CPU that's under 3.0GHZ. Windows 8.1 has proven to increase FPS in quite a few games so if you can, install it. Not much else you can really do besides get a better CPU. You can sell your current I5 for a good price and step up to a 2500K or a 2600K. That should relieve any and all CPU bottlenecks.

Which is your cpu usage?which is your gpi usage?which is your vram usage?which are your cpu,gpu and video card`s vrm temperature?

I think my cpu usage gets to 100%. GPU usage I've never checked, don't really know how to log that. Cpu never gets above 70c while gaming, GPU gets to about 67c, and VRM gets to about 71c.

Gpu`s vrm or mobo`s vrm

Check gpu usage with msi afterburner/gpuz and check vram usage and vrm temperature
Are your cards oced? If so how much?do you have your power limit set to 20-50%?
And recheck your cpu usage.
Try a clean installatiom of your cureent windows(make back up the origin games folder)

GPU VRM I meant to say. I have it OCed to 1100mhz GPU, and 1505 Memory. I have power set in CCC at 0% as I don't really understand what it does to be honest. I was told not to play with that setting because I could fry my GPU, and I figured that if it started artifacting or getting unstable I'd just back the clock off until it was stable but I haven't had any of that or any crashing at all.

EDIT: I take back what I said. Watching my resources in windows task manager while playing bf3 Im seeing 78-85% cpu usage.

That`s your problem you need to move the power limit bar to 20% or more your card is throttling itself due to a lack of input power/tdp limit that needs to be fulfilled

So I updated my drivers to the newest BETA released a couple days ago, and it runs much more stable now!
