Poor GPU Performance

Hi guys,

I've been having some issues with my graphics card as of late (It's an ASUS GeForce RTX 2080). It's been doing this thing where it will keep dropping frames for no apparent reason, dropping from 110+ down to below 80 and back up again, routinely. I can also see it when I have the performance overlay on in VR (Assetto Corsa), where it'll suddenly drop from 40% headroom to 0% and sometimes below, even when I'm not driving.

I ran a performance benchmark on Novabench, and during the GPU test I can see it dropping from 135fps down to below 100, just as it does in the games. Once the test finished, the test stated that my GPU was in the bottom 20% of all RTX 2080 cards tested, and that my GPU score is 12% lower than a NVIDIA GeForce RTX 2070, and 27% lower than a GeForce RTX 2080 (My Card) in the baseline comparisons.

Any help would be greatly appreciated. I tried a web chat with NVIDIA last night, and that didn't solve any of my problems. I've sent an email to ASUS, but I'm still waiting on a response.

P.S: I also tracked the GPU while running a Novabench performance test, and these were the results:

. 40% GPU Load
. GPU Temp - 44 Degrees C
. 52% Power Consumption
. GPU Voltage - 1.05v
. Power Consumption - 115w
And it says that it hit a performance cap due to Vrel: Limited by reliability voltage & VOp: Limited by Operating Voltage
 
What are the complete system specs?
 
Hi oxrufiioxo

It's got:

AMD Ryzen 7 2700
Asus ROG STRIX X470-F Gaming Motherboard
Team T Force Nighthawk RGB 16gb DDR4 RAM
Samsung 860 EVO 500gb SSD
WD Blue 2TB HDD
ASUS GeForce RTX 2080
Be Quiet! Pure Power 11 600w

Hi Caring 1,

It's a Be Quiet Pure Power 11, model:L11-600w
 
Download this and run Timespy. Post a screenshot of your results
www.guru3d.com

3DMark Basic Edition Download v2.31.8385

Download 3DMark Basic Edition for Windows- 3DMark is the world's most popular benchmark. The latest version introduces powerful DirectX 12 Time Spy and Nomad Steel benchmarks, each designed to challenge different types of devices.

I'm pretty sure vrel and vop are pretty normal on most modern Nvidia GPU to be performance cap reasons.
 
I'm downloading the file [Guru-3D.com]-3DMark-2016-spy.zip now, It's around 6GB.

My internet is pretty slow, so I'll let you know when it's finished downloading and I've ran it

Thanks
 
Yeah, I was worried about that.

I'm not familiar with how Assetto Corsa performs but you may be hitting a cpu bottleneck with the 2700X depending on what resolution you're playing at. I've seen other threads complaining about ryzen performance in that specific game hopefully someone who plays it will notice this thread and chime in.... Timespy is pretty hardware agnostic so we will easily be able to see how much your system is actually under performing vs other 2080s I think graphics score wise 10000-12000 is pretty normal depending on model and silicone lottery/ambient temps etc.


Keep an eye on power consumption while you're running Timespy you should be in the mid 200w range.
 
Hi again,

I've done some testing. On the Time Spy test, my PC got a score of 10,246. I tracked the GPU usage while that was running, and I think that it was working fine. It was at 100% load and the power usage was around 220w. Although when the Time Spy demo was running, it wasn't running at 100%.

The same goes for The Witcher 3, that seems to be using 100% of the GPU. It runs at around 100fps on Ultra at 1080p, but it still does drop occasionally to 80fps (That might be normal though).

When I tried to run Planet Zoo, it was stuttering like crazy and the GPU usage was all over the place. It was going from using 40% to 20%, and the game was staying at around 20fps with constant freezing and stuttering. That game is unplayable at the moment. The same issue was present when I ran the Novabench test again. It was only using a small percentage of the GPU, and it was suffering from frame drops during that as well. That might be why it says that my GPU is ranked in the bottom 20% of 2080s.

This is all relatively new to me, so I might just be asking dumb questions. Is that normal for a GPU to only utilize 40% of its capacity, and for the game to suffer because of it?

I'll attach the files of the tests that I ran, thanks again

What was Planet zoo's CPU usage at when the GPU was at 20 or 40%?

I have the same issue with Fallout 4 with my system. CPU usage maybe 60% but GPU usage at 40% and games FPS is very low. I cant seem to fix it. Some games are like that unfortunately.

Have you tried reinstalling the drivers? I mean, uninstall them, clean them with DDU in safe mode, and then installing new ones?
 
Witcher 3 can be pretty CPU heavy in some areas so your performance sounds normal. Your Timespy score seems pretty normal as well for a stock clocked card.

What specific 2080 model is this?
 
Hi Sepheronx,

I just had a look, it was fluctuating between 10% & 60%. It's really strange. The person I chatted with at NVIDIA asked me to try out an older version of the GeForce Game Ready Driver, but that didn't change anything. I didn't try the method you just gave, but I'd be willing to give it a shot!

It's an ASUS GeForce RTX 2080 oxrufiioxo, the sticker on it says it's a Dual-RTX2080-O8G
 
Ok that's a pretty budget Asus card as far as cooling goes.

If you haven't already I would download afterburner and setup a custom fan profile and raise the power limit to its maximum this should at the very least stabilize your boost clocks. I'm guessing your issues are game specific since Timespy/Witcher seem to be behaving normally.

I think as @sepheronx said a clean install of your drivers might be a good idea. If you're able to acquire a different psu that you can return easily like on Amazon in the 650 gold range I would give that a shot just to rule out your psu.


Also make sure your chipset driver is up to date with the latest x470 driver posted on AMD website.

I have got afterburner installed, but I haven't tried anything to do with a custom fan profile. I'll have a look into that and I'll have a go at doing a clean install of my drivers as well.

If that doesn't change anything I'll look into trying out a different power supply. Thanks for the help @oxrufiioxo, @sepheronx & @Caring1, I appreciate it!
 
I would also try the Final Fantasy 15 benchmark it does a good job of hammering your system and then giving you a score that you can compare against other 2070/2080 cards for reference. I don't think it's a large download but I can't remember off the top of my head.
 
yes. And please if it is working after it, let us know.
 
Your first example was a racing game, so I suggest you turn off render ahead targets. They put pressure on your cpu to send blank frames in case you don't change the input, however you don't ever keep the same input in a racing title.
 
Yeah I've messed around with all kinds of settings with the rendering on AC mtcn77, it just seems to have a weird occasional laggy frame drop every so often regardless of what's happening on track.

I'll have another look at that setting though, thanks
