AMD RX480 Strix GTA V Stuttering FPS

[RM_Forshaw]

Hey, so I have recently built my PC, with 24Gb of DDR3 Ram (Upgrading to DDR4 when I can afford to), a 8gb ASUS Stric RX480 and an FX 8370 8 Core 4.00GHz CPU. I am trying to solve stuttering FPS in GTA V, which can be as bad as skipping from high 40fps down to low 20fps

My settings at the moment are almost everything set to ultra except:
Grass: High
FXAA: Off
MSAA: 4X
Reflections MSAA: 4X
Particle Effects: High

The advanced Graphics are at minimum because I understand they affect performance drastically... I cannot seem to get rid of the stuttering and the game is barely playable whilst like this

For me the task CONTACTS IMPORT thingy, only appears after I launch a game. I start a game, ALT TAB out and open task manager and its there..

It doesnt seem to appear for me

Which frequency is your RAM? DDR3-1866, DDR3-1333, etc.

 

[RM_Forshaw]

Sorry, DDR3-1866

 

[Carnaxus]

Hmm. Doesn't seem to be a lack of power, as the PSU is 600W and your computer appears to only need 381W.

I don't think this is actually the issue, but usually the fan on the back is used as an exhaust fan. The "standard" airflow through the case is normally intake through the front, bottom, and sometimes side if there are mount points, and exhaust through the top and rear. Maybe flip that fan around? Who knows, it might help.

I unfortunately can't think of anything else directly related.

just try connect your display with displayport from gpu to your monitor get the right connections.

Are you sure this isn't a screen-tearing related issue? What Monitor are you running? Since you said:

"The microstutters at lowest settings are still extreme (120fps down to 68fps on some) however they are less frequent."

If you are running a 60 Hz Monitor with no Frame buffer sync (V-Sync, FreeSync) or no Frame capper you would be experiencing frame tearing and such related issues. If this is the case, enable V-Sync in the games settings or lock the FPS to 60 FPS. Again, this is assuming you have a 60 Hz display.

So I dont use a moniter per say, I currently just have a cheap 22" TV which Im using until September when I can bring my 42" 3D TV to University with me... And yes, my display is connected via my GPU

I am able to get a solid 120fps in Rainbow Six Seige and Doom on Ultra settings, however in Skyrim, Fallout 4 and GTA I have the same issue, however Skyrim and Fallout seem to max at 30 fps for some reason. Also, as I mentioned, my latest build is exactly the same as my previous build only with an improved GPU. Before upgrading my GPU, these games were very stable, even with my current Display

run 3dmark firestrike (free dmo version) with default settings and click on compare result after it. Copy the link from you browser and post it

This is mildly esoteric, but it could be that you have your RAM in the wrong channels. I think you're usually supposed to have the bigger sticks in Channel 1 and the smaller in Channel 2, and usually slots 1 and 3 are channel 1 and 2 and 4 are channel 2. From that 3dmark spec you posted, you have the smaller in channel 1 and the larger in channel 2. It's a bit of a long shot, but swap those around and see if it helps.

Carnaxus you may have solved it... initial tests look promising, I switched the RAM and started GTA, although it was on all low, it was a very smooth 85 fps with almost no stuttering (I expect to get some at some point)

Edit: No restarted on almost max and have a solid 52 fps playable GTA! Thank you everyone who tried to help and especially Carnaxus, probably would have been stuck without you all haha

RAM channels, the most subtle thing in your entire computer that can still bring even the best rig to its knees...or something like that. Glad we finally figured it out.

 

[helpstar]

in which slots are which Dimms now? you can use cpu-z if you don´t know it anymore

 

[Carnaxus]

He probably reversed them, so instead of Slot 1: 4GB, Slot 2: 8GB, Slot 3: 4GB, Slot 4: 8GB, he's got Slot 1: 8GB, Slot 2: 4GB, Slot 3: 8GB, Slot 4: 4GB.

 

[helpstar]

Probably, but the thing is, nobody knows for sure, how 3dmark is numbering the RAM. That´s why I wanted to ask RM_Forshaw directly.

I think this is another reason why you have the screen stuttering. I was following this thread because I had the same issue. The reason in my case was that I was using my smart TV as monitor and this created some sort of bottleneck, even with the game at the lowest settings. However, once I plugged my computer to a PC Monitor (although this was old, not 1080p, 50/60Hz and 2ms) I've got an average 38fps with the highest settings (it just a matter of change a couple of settings to reach the 60fps). Try to use a monitor instead of a tv.

Good luck!

The reason switching from your new Smart TV to an older monitor fixed the issue was probably something to do with how Smart TVs are computers in and of themselves, and do a bit of processing of their own before displaying an image; I can see where that would lead to stuttering.

lowering from 1080p to lower than that can increase game performance significantly 😉
