Game not using 100% of my gpu?

[Kag]

Im at 30% cpu 45% gpu and fluctuate fps 50-65, anyone know how to make it use 100%?

Wrong, you are thinking of CPU. Using 99% gpu means your pc in a good shape and all parts are perfectly balanced together. Your cpu 100% however is bad and will make your game stutter hell, fps drops and all that.

Wrong. Check any video game benchmark. You'll never see a gpu going up to 100%.
When the GPU hits 100% games get unplayable laggy.

stop spreading misinformation.

If your GPU is below 98% or so, in most of the games that you play, then you literally payed for performance that you are not using. If your GPU is at near 100%, and you are getting good FPS, then you have basically hit the the most idea situation.

There is a reason why pretty much every benchmarking video shows games sitting at around 98 to 99% GPU utilization:

I'll just ask this, what is wrong with my answer? CPU hitting 100% mean the same as GPU hitting 100%. They'll just bottleneck each other. There is no such thing as GPU 100% is good. If your GPU cannot hit 100% and your CPU isn't bottlenecked, then it just means you can pump up your graphic settings or FPS limit.

The benchmark or "Test" that they do usually doesn't lock the FPS and lets the GPU use unlimited FPS. You can just ask them if the GPU pumps out 200 FPS but your game caps the FPS at 144 FPS. Will GPU still be at 100% all the time? The answer is no, it'll hover around 50 - 70%. That is the most ideal situation because it still has leeway in case there is something heavy on GPU so FPS will not drop so hard.

You can adjust your settings until the GPU hits 100% and good FPS. But just be ready for a dip in FPS from time to time because the GPU doesn't have room for an increased load.

CPUs can be the bottle neck without hitting 100%. A game will rarely if ever use every core, use every core equally, and not all cores are equal either. That means your CPU can be a bottleneck to your GPU (aka the GPU is waiting on the CPU), even if the CPU is not showing 100% usage.

A big giveaway is that your high FPS and Average FPS are way over your 1% lows. Typically, if you have a CPU bottleneck, you will see a big gap from your high FPS (when the GPU is working at full clip) and your 1% lows (when you GPU is forced to pause and wait on your CPU to catch up).

Accept it or don't, but this is the truth, and PC enthusiasts have known it for a very long time.

You are right. Since Multi-core CPU was a thing, this has been the sole reason why coding for multiple-core is such a pain. The thing is that you can still see your CPU core hit 100% and you think to yourself, how can I improve this? The answer is, you cannot. It is solely on the game code/engine that gives out the job to the CPU. So, yes, if the game doesn't optimize the job given out to the CPU, you can get CPU bottleneck even though you are using i9-14k. Buying a new and better CPU doesn't fix this either.

So, if you see one of the cores hit 100% and the game stuttering as hell, but the report of all CPUs said only 20% utilization, this is why. It has nothing to do with the CPU at all, it is all the game code/engine fault if all of your CPU cores cannot hit 100% and bottleneck the GPU.

So it's poorly optimized for my CPU is what I'm hearing? Because my CPU coasts through anything else so it's not a bottleneck because of outdated hardware that's for sure, I'll mess around with my settings after-work and can't see if I cant get it stable, lowering my resolution is out of the question though as anything not played in my native 21:9 (2560x1080) looks like mud.

Playing in 4k , settings HIGH/ULTRA, I7 6700K, RTX4080, 32 GB RAM, SSD, 60 FPS smooth, 50-60% GPU load, 50-70% CPU load. It depends what framerate you wish. But for 60 fps, you don't have to blame your CPU :)

[Kag]

Yeah this is driving me nuts, Im playing the game now Low, Medium, High, Ultra. Nvidia Performance overlay is telling me Im using 20-30% cpu and it's always around 43% GPU. 70 Fps on low, 40-50 on medium and high and 30 on ultra. Why the hell are you not using my GPU more game what gives

[Kag]

DlSS Quality gives me 15-20 frames back but still fluctuates all well ill keep messing with it, but damn would like to see it work my gpu

Yeah, it's most likely a CPU bottleneck. Tends to happen at 1080p. Nothing you can really do about it. You can try increasing some of the graphics settings or even use supersampling (not sure how to do it on NVIDIA) to put more load on the GPU.

He has a 12900K that aint a bottleneck, especially not with a mere 3060

That is also wrong, GPU at 100% means the same thing as CPU. If you really want to get everything out of your GPU it should hover around 80-90%. If it hits 95%+ it means your GPU cannot keep up with the graphic setting and will not hit the max FPS you are setting (if there is one).

You are 100% wrong.

Nah he's right 99% or 98% is different then 100% for one. If you are at 100% usage that means any additional processed data (frames) will not get processed this will cause stuttering because the frame was not processed it was skipped. Some games can run at 100% with no issue but other especially on a non-optimized PC can struggle. All this is reference to 100% non-stop prolonged usage. It should if working normal bounce around and not be at a constant 100%.

Granted this is all speculative and dependent on a person PC and cause "context-specific" stuttering.

100% is normal but not all the time.

Yeah it's stuck at 43% gpu usage no matter what setting lol weird

Look like play with pcie x4 or x8 slot :P

what do you use to monitor GPU usage? use the OSD like msiafterburner.  getting 50~65fps at 2560x1080 with 3060 sounds about right.

[geraldow]

What could happen if your PSU can't cope with the load is:

Bad 3D performance
Crashing games
Spontaneous reset or imminent shutdown of the PC
Freezing during gameplay
PSU overload can cause it to break down

try useing a program like HWMonitor , windows task manger was saying i was using 19% HWMonitor told me it was 80-95%

Actually no. 99% is normal and great actually. On a CPU however you do not want 100% usage.
