Graphics Cards

Hello, 

i experience a regular slowdown despite monitoring programs reporting constant fps without drops.

this happens in ALL 3d games.

If the game is less demanding and the gpu runs below 100% it may take some time, up to maybe 1 hour for this to occur. If the game is gpu intensive and the core runs on 100% constantly, it starts almost immideately.

It is not really a stutter or frame drop, rather it feels as if the game itself runs slower for a split-second, this happens maybe every 1 to 2 seconds.

so far i have tried:

-clean driver install (DDU), several versions, on 19.5.1 atm

-setting power limit in wattman to 50

-enabling high performance mode in windows

-checked RAM with windows-tool

-googling for a few hours

my specs are:

MSI rx480 Gaming 8gig
core i5 4670K @ 3,8 Ghz OC
win 10 Pro x64 (latest updates)
8,00GB Dual-Channel DDR3 @ 1600MHz
MSI Z87-G43
coolermaster b500 v2 PSU (500W)

i think i can rule out temperature as the cause since i monitor it and neither gpu nor cpu ever reach much more than 70°C. i realize that i should maybe upgrade RAM but it never reaches full load and especially in less demanding games there is usually a lot left.

any ideas what might cause this?

sorry for the language, english is not my first language

thanks for your time.

trying to bump this since no one answered. would it help to upload a video of the phenomenon? would be a bit of a hassle since i do not have relive installed nor a youtube account...

I noticed something else that strikes me as weird: when activating the performance overlay, it consistently reads the VRAM as almost empty. i'm talking less than 1 GB despite high texture settings in games like Assassins Creed Odyssey...maybe the VRAM is faulty? any way to check that?

Update: I upgraded my RAM, now on 16Gb DDR3@1600Mhz, issue still persists. also, still hoping someone might have any ideas

yay more updates for myself: i found out that in some games, enabling vsync fixes the issue which seems to be inconsistent frametimes. in others, it does not though.

itzneof I am having this issue right now EXACTLY, I also have a rx480. Did you manage to resolve your issue?
