RTX 4090 problems

Brand new rig, all components. Many times I find that there are big FPS drops in games even tho only like 65% or so of the GPU is being used. Why doesn't my computer use as much of the GPU as needed to maintain a relatively constant FPS (144FPS set by me)? How can I solve this issue?

What games?

Games compute their core game loop on the CPU and then a game that values high performance will utilize performant compute shaders and geometry shaders on the GPU, these can range from being poor in design to be really good in design.

There is all sorts of reasons why you never make 100% utilization in many games the above is one of them. Other areas are poor settings or poor combination of parts.

seeing as you said its new computer then this is most likely your issue you need to spend time tweaking the computer. This means a whole range of things far to much to list here. Like days of tweaking ahead of you.

What resolution? you play at ultra? you overclocking?, BAR? DLSS? all relevant information

Do a test with 3d mark spy if it looks consistent then you know its in discrepancy per game or if it shows you the same sort of results that you are getting with the games then you know its your hardware/computer overall that needs attention.

i guess got to ask too you got the driver installed?

Steam isn't letting me download that app

1440p, maxed out settings, no OC, wtf is a bar? No DLSS

Is 3DMark Spy free? Steam wants me to pay

I got an email notification saying Malneb had replied but I cant see that comment he apparently made at 4:43PM

Well you need to do some tests, hard to suggest do this do that without really knowing your computer firsthand at this time and what it is doing irl. Do some benchmarks and look at why you are get bad FPS you will only work these out by testing.

You said max setting in games so then you need to drop the settings things like post processing effect and resolution scaling in these games or you need to overclock the card if you want to max everything out.

BAR is a setting that you need to turn on for performance you will have to see if your motherboard supports it AMD board with NVIDIA GPU may not support it i know there is some support but i don't mix parts like that so i don't know fully.

Sorry i thought it was free its not so i deleted the post. I feel like it was at one time but this program goes back over 20 years so i could be just thinking it used to be free idk.

There is no real issue. It is how the game is written and what resources are used and where.

A user can effect fps by changing the level of each graphical effect. Some of those do not have to be set to highest levels as it may not actually be visible thus wasting resources.

That is a user skill in identifying the graphical effect's visual qualities and making an adjustment which in turn will effect resource usage. i.e. CPU and RAM, plus GPU and VRAM. Certain effects and methods are more hungry on resources than others.
Each game varies in what you can change that is dependent on what the developer decides upon.

To increase that usage to near 100% may involve a higher level effect which is just not visible, thus rather pointless and probably reducing fps.

I usually use 3DMark to make a perfomance comparison with similar hardware. If you fall within the main distribution of a benchmark curve then be happy everything is basically OK.

Is 3DMark safe or can it fry my PC including any component?

This is the same test btw

So that is telling you are in the 99th percentile which is obviously good and it tells you some basic things like you can determine some rough expectations from that chart like it would be obvious if your were under performing against others with similar hardware.

but you don't really need to look at that as its mainly just a chart for competing against others.

You need to run benchmarks and calculate your 1% low FPS basically the reason why you are getting dropped frames or frame spikes or what ever is happening could be a few things. but this metric is about it is analyzing why.

There is other factors and it starts to get involved. But basically what you are trying to work out is why you cannot have a constant stable game/FPS when you are in the 99th percentile you should be doing ok inside games because benchmarks run harder than games most of the time.

Just look up online there is plenty of information out there but it encompasses a few things which are hard to explain and even setup.

More so did the image seem stable when the benchmark was running? or was it a choppy mess? because it should be running smooth on the computer.

it does also come down to some games as we already mentioned just some games cannot be run max everything.

Afterburner is good if you really want to see what the computer is doing in the game but that takes a bit to setup properly you would have to read up on it.

use it to Look at your frame time in the games 144hz monitor so 140fps or more would want around 6ms frame time.

Also here are the tests in 4K without a 4K monitor

It's not the GPU it's the Ryzen 7900x
These chips dip hard in games unless overclocked to stabilize the clocks.
Basically you found out that this chip has a array of issues keeping up frames mainly due to how they put cache on the CCD

Ah ****. Okay. I got 2 questions

1) Would overclocking fix this issue?

2) If I don't wanna overclock coz I am a noob, would switching over to 4K instead of 1440p fix this issue? Since AFAIK, no matter what, in 4K it's 99% your GPU that will be rendering the pixels/frames, not your CPU.
