Huge GPU usage drops

Kobo99 · May 26, 2017

Like the title says, I get huge GPU usage drops in any game with my RX 480, here are a few examples:
Overwatch: 90FPS locked and then 15FPS drops every minute or so
Clustertruck: between 55 and 30 FPS and then drops to 10FPS every 5 seconds or so
Minecraft: 15-20FPS locked

Here's my GPU activity curve (blue) in Wattman while playing Clustertruck:

I've had this problem since October, I'm really getting sick of it..
For more info check out my previous post about the same problem here: http://www.tomshardware.co.uk/answers/id-3349795/low-cpu-gpu-usage-gaming.html

have you tried looking at your vram usage? Doubt that would be it with 4gb on the 480, but if the card is faulty and has a hardware issue it's possible you're running out of vram. Have you another GPU you could drop in to see if it's the same? Best thing is to take a pragmatic approach and rule out one variable at a time. I know thats easy to say. (don't wanna sound patronizing)

I have a question, are you currently overclocking the cpu and or gpu ?
if the answer is yes, I suggest you turn it all off, and run some test to eliminate the overclocking being the issue.

What resolution are you running your rx 480?

SgtScream :

just saw your sig.....are you really running that I5 at 5ghz with a hyper 212. thats some OC. what vcore? can't believe it would be very stable at that speed. Your vcore must be really high, or else you've got an amazing chip. lucky!

SgtScream · May 26, 2017

The vcore is it's max 1.52v as I want to build a new computer lol. I recently had to drop the frequency 100mhz due to instability during game play.

SgtScream :

holy guacamole!! thats awesome! i'd say it rips through everything

fair play.

SgtScream · May 26, 2017

Yeah, it hold's its own, paired with my gtx 1070 running at 144hz 1080p. I just have no idea how long it will run at such a high vcore. I keep it turned off when not using it so the cpu won't degrade as fast.

SgtScream :

yeah, i here ya! I'd say it runs fairly hot alright. 24/7 use at that high a vcore is prob gonna half the life. give the chip is already a few yearsold, looks like youre plan for a new rig is coming to fruition!

Roland Of Gilead :

I tried my old R7 260x out and have similar issues (I did this a few months back, I should check again, just to be sure)

The Paladin :

I was overclocking my i5 from 3.5 to 4.0 GHz but going back to 3.5GHz didn't help..

Kobo99 · Jun 3, 2017

SgtScream :

I play at 1080p but weirdly enough most games suggest me to play at a much lower resolution.

SgtScream · Jun 3, 2017

In control panel, under power settings. Is your power settings set to "high performance"?

The Paladin · Jun 3, 2017

Have you tried to run HWINFO and see if the CPU or GPU Max'es are being pegged (ie throttling?)

Kobo99 · Jun 3, 2017

SgtScream :

Where do you do it ? In Wattman ?

Kobo99 · Jun 3, 2017

The Paladin :

I have, but I have no clue of how it works..

Kobo99 · Jun 3, 2017

Thanks,

It was on "Energy Saving", I'll try some games out right now!

Kobo99 · Jun 3, 2017

It worked! I'll post an update soon, I'm re-downloading the Witcher 3, so if it still works in that game I'll be the happiest man alive, I've had this issue since I got the new GPU and PSU around CHristmas so I'm extremely relieved..
Thank you SgtScream!

SgtScream · Jun 3, 2017

I really can't believe how many best solutions I've gotten with that suggestion.

Kobo99 · Jun 3, 2017

SgtScream :

I remember switching to "High Performance" but now I recall I did it with my old PSU, anyway, keep up the good work ^^
