Frame rate issues with r9 390

[TheBiggestRas]

Hi.

I recently upgraded my pc with a radeon r9 r390 Nitro, and a new PSU. However i'm still struggling to run games like the witcher 3, just cause 3, skyrim and fallout 4 even on low settings. I've been monitoring my gpu's activity and it's all over the place, it can go from 100% to 30% to 0% at any moment even when i'm just browsing the web. I'm willing to upgrade my pc, i just have to find out where the problem is.

Specs:
Psu=Corsair AX 760 PSU
Cpu=AMD FX-8350 8-Core Processor(Overclocked)
Motherboard=ASUS Sabertooth 990FX R2.0, Socket-AM3+
Ram=Kingston DDR3 HyperX 1600MHz 8GB
Gpu=Sapphire Radeon R9 390 8GB GDDR5 NITRO
1TB HDD
1TB SSHD

Thank you!

Cant see issues with system. Just cause 3 has big amd optimisation issues...see my thread on it. Fallout 4 is the same...turn off god rays in the config file. JC3 struggles on fx CPUs...even on i5s. For reference I get:
JC3 1080MAX 65fps av....drops to 45 min
Fallout 1080 max god rays off 65 drops to 38

That's with 1130/1675 overclock. Those games are tough on AMD

I tested your solution by turning off god rays in fallout 4 and setting the settings to medium, however i stil get 30-35 fps. I'm starting to wonder if the problem might be one of my components not running at it's full potential, however when i run a furmark on my gpu i get an average of 70 frames in 1080p. What do you think might be the cause of this?

Turn off vsync in fallout 4. Its the ipresent setting in config file. Also godrays must be turned off in config file and then file set to read only so game can't change it.

Jc3 and fallout are two of ,the not so well optimised at the moment sadly.

 

[TheBiggestRas]

I made sure that both god rays and vsync was turned off, however i still get 30-35 fps with insane drops when entering cities. I've tested oher games like The witcher 3 which i should be able to run at medium at least, but i still only get around 35-40. Skyrim is also running poorly with huge drops that really ruins the experience. I know that Jc3 isn't well optimised. One thing i find very odd is that my friend who has the exact same pc as me, the only difference being that he has the r9 290 and 16 gb of ram runs Jc3 on max settings with constant 60 fps.

My problem is that this occurs on multiple games.

 

[TheBiggestRas]

I've been wondering if that was the problem or not, but i wasn't really sure. I'm going to upgrade to 16 gb of ram as fast as i get the oppertunity. Do you have any recommendations?

Thank you for your help good sir!

 

[TheBiggestRas]

Thanks. I will look into it and see what i can afford.

Thank you very much.

Well now I'm intrigued. In JC3 I get frame drops and CPU gpu are BOTH not maxed. BUT task manager says no disk access is occurring despite swap file being used according to afterburner.

Fallout doesn't use all 8gb ram but I am thinking 16gb may be required for jc3. Hmm

 

[burgessanthony]

Looking at benches or every modern game...16gb will do nothing for av times or min fps. Don't waste money! Jc3 maybe the exception I think.

 

[TheBiggestRas]

I've also looked at some benchmarks, and one of the setup used for the witcher 3 wasn't that much different from mine. However he got an average of 55-60fps in the most demanding places where i just get 40-50fps on high with insane drops. I'm starting to wonder if one of my components might be defect.

 

[burgessanthony]

Do you use afterburner or other monitoring? would be good to see what is going on during gaming. - CPU usgage vs FPS vs GPU usage.

Don't forget, your FX won't deliver the same performance as a system with a new i5 in many games; they just are not as good right now. that MAY account for your frame drops, but may not.

 

[TheBiggestRas]

I use afterburner. I noticed that my CPU usage is somewhat stable under loads while my GPU usage is all over the place. My RAM usage sometimes goes insanely high.

 

[burgessanthony]

Take JC3 as an example....what is your CPU usage when you notice FPS drops? Is it above 85% and is your GPU usage not 100%? if so, some CPU bottlenecking happening.

One thing to try in that game - use radeon settings to override anisotropic filtering and use 16x. The AA in the game is iffy for AMD. I have increased min FPS from 40 to 50 by doing this. Now getting 70 average with all maxed out - this should be similar to what you get also.

 

[TheBiggestRas]

My CPU is around 65% while my GPU usage is 100%. I tried to use Radeon settings to alter the anisotropic filtering to 16x did help a small bit, but not much.

 

[burgessanthony]

Ok. And your at 1080, vsync off, all settings very highest with other stuff on (global lights etc?)

 

[TheBiggestRas]

Yes and i still get horrible fps.

What is the MHz of the GPU? My r390x only runs at the MHz needed. it can run at 375 MHz and show 100% if that all that is needed. Turn off power saving to stop the jumping up and down issue.
