how to force GPU usage to 100%
hi there!
i've bought an R9-290 a few months ago and whenever i try to play games to GPU usage goes up and down like crazy, and the temps is the same no matter what (63). it doesn't move from there as if the card is programmed to stay on that temp no matter what and that causes the usage to go up and down like crazy. this causes my FPS to be low and unstable. i've been all over the internet looking for a fix for that and even bought a higher res screen (1080p) which didn't help. the only time i see a stable 100% is when the res scale in BF4 is on 200%, and that's unplayable.
can someone please help me????????

Its a 100 % bottle neck thanks to your Amd cpu, now i have also been using the same pc specs as u said, i simply sold my fx 8350 and moved on to INTEL chipset mobo and cpu, at first i was using my r9 290 on z77 extreme 4 with i3 at 3.3 ghz, i honestly saw a ton of performance improvement, next thing u know i realised that amd processors were just good at overclocking and nothing else, after using this setup for 3 weeks i moved on and installed an i7 3770k overclocked to 4.4 first on stock cooler, then 4.8 ghz on custom water loop, long story short cutting all the bullshit out !!! Remove your mobo and cpu buy some intel shit and voila happy gaming, and if this do3s not work u can punch me in my face for wasting your money !!!

You definitely should try "core unparking" as You got a FX 8350!
A lot of AMD BF4 players could get rid of the FPS drops by doing that.

If that does not help, reinstall BF4 and reinstall video driver AFTER that.

Too avoid redownloading BF4 do this:

    Goto BF4 installation directory
    Backup Data, Update, Update2, Update3 directories
    Deinstall
    Copy Data, Update, Update2, Update3 back to the BF4 installation directory
    Reinstall BF4

By doing this Origin starts installation, gets the core files and some other stuff, finds the data files and proceeds straight to the installation. It takes just a few minutes.

Stay away from overclocking as it is useless concerning FPS drops. And don't mess up the BIOS!

Gigabyte GA-990XA-UD3
or
GA-970A-D3P

these are currently my only options as the selection in my country is few.


Those are good option, but get the 990 chipset if you can cause it will have better VRM for overclocking and also they both should support the FX 8350 out the box.

Post the model of the motherboards you're considering and we can check. BIOS update may still be needed before supporting fx-8350.

what about a 990X chipset?
i'm talking about this board Gigabyte GA-990XA-UD3

When you overclock I would set the CPU voltage to manual to make sure the motherboard doesn't crank it way up.

When you set it to manual make sure it isn't set to anything higher than normal for the time being

But..um seriously you need a better cooler. The stock one barely manages at stock clocks

thanks, i'll measure the clocks while gaming.
but it seems i was wrong again: i checked the box again and it says its "rev 4.0". having said that, according to the support list on gigabyte's website (http://www.gigabyte.com/support-downloads/cpu-support-p...) the 8350 is still not supported.

can you recommend a cheap MOBO for the FX-8350?


Any 970 Chipset should be fine.

it's not that simple, because there are 2 versions to my MOBO: rev 1 and rev 3.1. i have revision 3.1, which supports AM3+.
http://www.gigabyte.com/products/product-page.aspx?pid=...
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

it even says that it supports AM3+ on the box. what i'm trying to figure out is whether or not my MOBO is bottlenecking or how i can check that.

it also doesn't specifically list fx8350 in the cpu support list either...
http://www.gigabyte.com/support-downloads/cpu-support-p...
one bit of good news is that the mobo does support other 125W cpus however, so you are unlikely to blow up the vrms on the mobo... (some older mobos only went up to 95W so a 125W cpu had the possibility to damage the board, mainly the cheap ones though)

You'd need to monitor the clocks on the individual cores when gaming (under load). If the clocks stay up nicely it should be ok. I believe amd had their own little software for that, the amd overdrive?
