Poor FPS with R9 390 and i5-6600K

[Glennman]

Hi guys, can anyone suggest a solution to the performance issues I've been having since buying a new PC 2 months ago?

In GTA V, Fallout 4 and now Doom, I get very poor FPS. I've just got a steam refund because Doom was down to 30 FPS. Fallout struggles in rooms with "artificial" lighting (eg. lamps, spotlights), and GTA gets to about 55 FPS only once I toggle Vsync off, then back on again (otherwise 30).

I ran 3d mark and get the following results at normal GPU clock speed (1040):

3DMark Score
11685
Graphics Score
16279
Physics Score
6442
Combined Score
6164
Graphics Test 1
66.91 fps
Graphics Test 2
72.34 fps
Graphics Test 3
115.82 fps
Graphics Test 4
52.33 fps
Physics Test
20.45 fps
Combined Test
28.67 fps

It looks like the physics score (which I've read might be more representative of the CPU) could be the problem. Some tests scored as low as 18, with overclocking to 1140 only registering around 21-22. From looking at similar 3dmark scores I should be getting around 30+.

A friend suggested to set the fan to 100% to ensure that CPU throttling isn't taking place. I've done that but it doesn't seem to make a difference.

Any ideas? Help is most welcome! Really spent a lot on this PC and the performance is really really disappointing.

Sapphire R9 390 (latest crimson driver that was optimised for Doom - 16.5.2.1)
i5-6600K
Asus H170 pro gaming motherboard
8 gig ram
Windows 10
850 EVO 500G SSD

Thanks

Just a follow-up to note that I've run a program called HWinfo64 to see if the CPU is being throttled. Doesn't look like it is (according to that program), but CPU usage in Afterburner is 100% in the Physics and Combined tests in 3dmark. I expect that is the point of the test, but still should be getting better results. I played Fallout 4 for a bit and a section underground (small rooms with floodlights) ran terribly while it was smooth as soon as I got outside (which you'd expect to be more demanding).

Help is most welcome, I'm running out of options here!

I honestly don't know if this will be any use, and I'm at work so sorry for the limited information, but check your settings in AMD crimson. On the page where you tweak the settings for individual games, there is a tab for 'global' settings.

I had the EXACT same problem, and tweaking the settings in there seems to fix it. I don't know exactly what setting it was, and because I'm at work, I can't check, but hopefully something in that page will help.

If you don't have any luck, I'll have a look when I get home to see what setting it was. good luck!

Hopefully a definite solution to this arises soon, I was about to place an order for those exact parts to put in my new pc.
