CPU: I7-9700 (non k)
GPU:RTX 2070 super
Ram:1x16gb 2666mhz
PSU:650 W

My gpu is most of the time at 70-90% usage in games and i've tried a lot of things like doing a clean install of Windows, deleting drivers and updating them, etc. None of these "fixes" worked. There's literally no way im getting cpu bottlenecked and my settings on Nvidia are on maximum performance. This issue is really annoying. I play games at 1080p and my monitor is 165hz G-Sync compatible.
Any tips that would fix my problem would be appreciated.

You basically just said that people are better off with a 3080-3090 for 1080p as it will never even use close to it's full capacity.

No, not even close. I was getting 50-80% on my gtx970, and even when moving upto my current 2070Super I'm still getting the same rough results from the same games, since I'm also using a stronger cpu which provides higher fps, so a higher workload comparatively.

1% usage or 99% usage is the exact same thing, there's no difference to the output to the screen. The difference is when the frame changes and demands more resources are used. If usage is lower, there's more room for expansion. If you are at 98% usage, an intense frame or frames can and will put that to 100% and then there's nothing left...

Not specific enough on the PSU model. EVGA has tons of models.

1 stick of ram will decrease frame rate and make the GPU have to work less.

A 2070 super is overkill for 1080p. Chances are your CPU is the limiting factor in most cases at this resolution.

EVGA 650 N1, 650W, 2 Year Warranty, Power Supply 100-N1-0650-L1
thats is my PSU

and btw i've watched gameplays by people with the same GPU AND CPU as me and they are at 98% gpu usage

650w is enough. A good 650w. A PSU of the N1s quality should not be put anywhere near an i7 and 2070 super.

I doubt it is the cause of "bad GPU performance", and honestly I don't think anything is wrong here. You are using a GPU that is going to be held back by most processors when running at 1080p.

So are you saying my performances are normal?

Aside from things like drivers, 3rd party software, and the psu, the single stick of ram is a flag.
The cpu works together with the ram to deliver pre-rendered frames to the gpu, but you've cut the memory bandwidth in half using just one stick.

would you recommend switching to dual band even if i will get stucked at 2666 mhz or should i change my motherboard too?

No need to change the motherboard for that, unless you have an entire memory channel broken...

'Stuck' at 2666mhz is fine; Intel build isn't as picky about ram speed. The single channel mode is hurting you more.

-It would be safer to buy at 2x 8GB kit...
-You can opt to just add another stick, but you have to do testing to make sure the 2 sticks are compatible...

Ok i will buy 8x2 or add another 16gb ( i will test the compatibility before buying it) thanks a lot man buying a new mb would've been a pain in the ass. would u recommend buying a 1440p monitor? the other guy told me that my gpu is getting held back while playing at 1080p

Ya'll realize you are all looking at it from entirely the wrong angle, even backwards.

Usage is Not how much of the gpu is used but how much resources it uses. Very important distinction.

Resources are things like speed, bandwidth, vram, cores, voltages, whatever. You are using 100% of the gpu, the gpu doesn't need to use 100% of its available resources to do so.

Think of it like hammering a nail into drywall. YOU will use 100% of the muscles in your hand to hols the hammer. YOU will use 100% of your muscles in your arm to swing the hammer. You will NOT need to use 100% of the strength in your arm to do so. You'll only use a small fraction of strength, even if you are using every single muscle.

Same with a gpu, it works to the best of its ability, working at 100%, but doesn't need to use the full extent of that ability to do so.

Those other ppl with 98% usage are actually in a worse position, their gpus are working harder, using more, just to get the same results as you get using 90%. It means they only have 2% gpu resources left before getting bottlenecked. So if they have a giant explosion, lots of physX and vectors and particles, and they hit 100% usage, they just ran out of strength, and fps goes in the toilet.

If data running through the vram only uses 6Gb,and your card has 8Gb of vram, that's 75% usage. Doesn't mean the data gets pushed through any slower, it's still getting pushed through at 100% of the vrams clock speeds and timings, it just doesn't need to use the full 8Gb of vram to do so. Someone at 100% usage is using all 8Gb of vram, so what happens when they need 8.1Gb, the data is slowed down a cycle, fps plummets due to the wait. You usage could spike could go upto 7.9Gb of vram, 99% usage, and still not get capped.

You are FAR better off never coming anywhere near 100% usage, it means there are still available resources the gpu Can use when it has a need to, depending on the scene, and doesn't take a hit the same as a gpu that is resource capped and has nothing left to give.

Punch something as hard and fast as you are physically able to. Give your utmost, 100% power in that swing, that punch. =20% usage. Why so low? Because you are not using 100% of the strength in your LEGS to punch something, you are not using 100% of the strength in your other arm, only the One ARM. You might use your legs and arm to stand, to balance, but that's not the same as using all the combined power your legs and other arm have.
