Constantly fps drops with RX 480

[Ozzy]

Hey guys, im playing SW2 for a few days now and since the first day im having constantly fps drops (minimum 35). I tried actually everything. I disabled all of the effects, set all the settings to low and even tried to play on 720p with 4:3 scale, and it always drop the fps. Im guessing it could be something to do with the colors from the game, since it drops specially when i shoot someone or when im surrounded by enemies. It seems that it always drop when there is too much coloured stuff around the screen. MSI afterburner will always show my GPU use in 100%, even with the lowest settings so idk if this is right. Im using the latest drivers from AMD. Does anyone have a tip/solution for me ?

OBS: I have other games running smoothly on my pc on ultra settings in 2560x1080, like DOOM, Overwatch, RE7, Battlefield 1, etc.

GPU: RX 480 8GB SAPPHIRE OC
CPU: AMD FX 8320
8GB RAM CORSAIR VENGEANCE.

Thanks for the attention.

If your GPU is at 100%, what is its temperature?

Max 75ºC, but usually 68ºC~72ºC

Well since i have no answer, i did manage to make it better by changin two configs in Radeon Panel. I changed the mosaic mode to "use the app settings" and the quality of texture filters to "performance". Idk if thats the name of the options in english, so any doubts just talk to me. Thx.

The CPU and low amount of RAM should 'throttle' the other games too one thinks?
(well DOOM is a VULCAN supported game, and Overwatch look like.. well..)
I had an FX 8350 as my previous build, and well.. only thing I can say it at it were at least cheap! Even cheaper when I sold it a year later!

I have some major slowdowns launching my toxic RPG into a huge crowd, (not been using anything but melee weapons until just recently)
But neither the CPU cores or the GPU hits 100% all the time.
And it's hardly noticabe when watching the FPS.

without the ram speed and actual anticipated performance, it is sort of hard to tell.

The GPU is probably not being fed fast enough to keep up, though. That's just my educated guess. It would make sense that lowering the settings helped it, since it didn't have to wait to be fed quite so much.

I'd expect slower paced games with less going on to run better -- but doom and vulcan should be performing well.

The 8GB of video ram is probably more than the game is using, and 8GB of system ram probably is enough provided there aren't a bunch of browser tabs open or something.

Uh anyway what is your CPU utilization looking like? And is loading the game/transitioning between levels quick compared to other games?

Do you have serious sam 3 or another cro-team/hog wild/devolver game to try in comparison?

This game runs well on most modern cards; I have to expect that you have a bottle neck and it's not the RX 480.

Unfortunally, i don't have other games from cro-team/hog wild/devolver. The CPU usage is around 40~65%, rarelly going above 65%. Idk if the afterburner is showing wrong numbers, cause its really weird. Sometimes im in the same place and GPU usage goes to 0% to 100% and back to 0% in two seconds.

I have similar to your specs, OP, so here's what I did to fix FPS drops and stuttering in most games.
First of all, update your video drivers. Then go to your Wattman settings and do this

But instead of setting 1050, set your last three voltages to 1120 or you can try 1100, at your own risk. Mine rx couldn't handle 1100, so I settled with 1120. This way you will have proper current and the gpu will handle max frequency much better.

Second, non over-clocked FX CPUs are really frigging bad at games. They cause all kinds of stutters, lags and FPS drops. I bought proper water cooling and managed to get my FX 8300 to 4.4 on 1.45v. But I won't advise overclocking unless your are 100% sure in your skills.

Third, I bought second 8gb Ram stick, so the memory would work in dual-channel mode. This alone gave me a decent FPS boost. Mind though, the RAM should be the same as yours. Same timings, latency, frequency and manufacturer.

Correcting voltages should do the trick, but if this still won't be enough I suggest wait a little bit and think about upgrading to something less problematic, voltage hungry and weak. Like, new Ryzen CPUs released in April or you can buy extremely expensive 4 core Intels right now. Which I would strongly advise against.

Playing on Ultra with 100+FPS. Rare drops to 60-70. Mostly because of weak CPU cores.
You are getting better results in other games, because these use more GPU power than CPU.
