30 fps Bottleneck in Shadows of Mordor Benchmark with MSI R9 390 8G

[Caleb Perkins]

My friend's PC build has been struggling to get past 30 fps after switching from a GTX 770 to an R9 390 8GB by MSI.

Remainder of build follows:
CPU: AMD FX-8350 8-Core @ 4GHz
MoBo: AsRock Pro 970 Pro 3 Rev 2.0
Memory: 16 GB of something (he didn't say, I'm assuming something decent)
GPU: AMD R9 390 8 GB
PSU: EVGA 750B

Initially thought it was a PSU issue hence the upgrade to the EVGA from a Corsair C650. So I assume that it might be a CPU issue but Idk.

Thoughts anyone?

What resolution? try lowering the resolution and see if there is a huge difference in FPS, if so it's a CPU bottleneck, 650w is more than enough for it, so I think it's the cpu, try overclocking it and if it's not fixed get an i5 CPU

monitor temps of the cpu and gpu, cpu overheating will cause this.

install amd overdrive and check your cpu's thermal overheads especially at full load

amd cpus have a low throttling temp


did you remove the old gpu drivers?

did you install the newest drivers from the amd website?

turn off vsync? and all of its various settings? ( i'm looking at you half-vsync)

motherboard bios is up to date?

Ended up being the motherboard itself, probably not enough VRM's or something of the like with such a power hungry card. It now runs Mordor at something like an average of 95 fps and a minimum of 61.

4+1 power phase design, and no VRM heatsink. It's not designed to have a FX 8350 on it. It's very likely throttling. Your graphics card is not what's causing this, other than a slight increase in temps inside your case, compared to any other graphics card. Consider having a fan blow ontop of the vrm mosfets and consider lowering voltage and clock speeds if you still don't get good results.

Ended up getting an Asus M5A99FX Pro R2.0 and runs everything like a charm. Someone please select my answer as a solution so this thread can be marked as solved, can't do it myself.
