GPU not using 100%

[dioni]

I'm using a Rtx 2070 and only in TW3 my GPU uses around 60% which keeps my fps at 50 fps, I checked if it was bottlenecking but the CPU is at 50% in-game, what do I do?

What CPU do you have, and did you try reinstalling your GPU driver?

I have a i7 7700, I'll try to reinstall the driver

Yeah that sounds like an issue with the driver, even a 4th gen i7 can do a decent job at handling a 2070 because it's basically a 1080.

I reinstalled the most recent driver, didn't work

if vsync is enabled, it will go to idle state after the next frame is ready before being sent to the display

if vsync is disabled and you are not getting 100% gpu usage its a game engne limit or cpu bottleneck

[hawkeye]

TW3 does its own vsync and also has a frame limiter setting. Check those.

Cpu and gpu both at less than 100% doesn't mean there is a problem. 50 fps might be a problem if the game settings are correct (and maybe the nvidia control panel).

Use msi afterburner (or hwinfo64) to check if the cpu or gpu is being throttled by temperature or voltage.

What does the per core usage on the CPU look like? Sounds like the CPU has hit the per core performance ceiling and simply cannot feed instructions to the GPU fast enough to keep it busy.

DX11 and earlier all have a common limit of one CPU core issuing instructions at a time. One of the major benefits of DX12 and Vulcan is finally allowing multiple cores to issue instructions concurrently (DX11 allows all cores to issue commands, but not concurrently. DX9 and previous designates a single core as the sole source of all GPU commands).

Depending on the game and settings, this limitation can easily cause both the GPU and CPU to be under utilized. This why gaming rigs still emphasize CPU's with high per core performance. Most games are still limited by this metric in terms of how quickly data can be issued to the GPU.

If you have any graphics settings set to low in your game, try seeing them to at least medium. Low settings are often fallbacks for legacy support and shift more graphics work to the CPU. Higher settings typically assume a powerful GPU and shift as much work that was as possible accordingly.

a CPU btw can bottleneck at 50% already a GPU. a 7700K could theoretically bottleneck already at 12.5% as if the game is only able to utilize 1 thread then, then the CPU will never reach 100% load. Which is perfectly normal.

I think that is unlikely.

TW3 is a cpu lightweight game e.g. my i7-2600 will do 100+ fps at ultra 1080p with a 1080ti.

I think OP's gpu is thermal or power throttling. On youtube there is an rtx2070 at 50C 100% usage getting 90 fps with a 6700k. If OP's gpu is at 80C as he has said on the TW3 forum, but 60% load, then it's probably cooling and the fan profile needs adjusting.

My 1080ti won't run at 100% load on TW3 and other games. The reason is that I have limited the temp and power in the aorus control panel. With high-end gpus it is necessary to check temperatures and power and adjust settings accordingly. Even the default settings may limit performance.

Also OP may have to OC his gpu as TW3 is graphics heavy.

As OP has only just bought the game he may have the in-game settings set up incorrectly, such as the fps limiter.

are you playing on ultra? is hairworks on? what's resolution? are you locked at 50 fps?

I'd cross check with other games to see if any of your games are being maxed out

[waltc]

* Play at 3840x2160
*Play at 8x FSAA
*Max anisotropy
*Vsync off
*Turn all other eye-candy on in the game (like DoF, Ultra shadows @ 4096)
*Max texture size @ 4096
*Make sure you do not have your GPU throttled for power consumption/heat, etc., as these considerations will always lessen the load your GPU will carry rather than increase it.

In the W3's .ini configuration file there are a lot of variables that you can can crank up far beyond their defaults if you wish. Should experiment with these. Several of them will crank up to values > than their Ultra settings in the game--although what effect they have on image quality is debatable--you have to experiment and see.

*Bing/Google "Tweaking Witcher 3," etc.--there are many guides on how/what to do.

W3 shipped in 2015, and is somewhat light on demanding resources from the GPU compared with other games that have shipped more recently.

***Basically, when you turn up the eye-candy to the max and get the .ini set like you like it--then you are done. Enjoy the game at that point, and worry not about the "load" percentages some monitoring software is providing you--if it's a lower "load" then all it means is that you are rendering everything the game has to offer in terms of image quality and your GPU is so powerful it has horsepower to spare after doing all that the game demands of it...;)

i think op's concern's that if both cpu and gpu're below 100% his fps's unnecessarily limited. logically he should get more fps until one or other hits 100%.

btw did op check that cpu % isnt average but for highest utilized cores? if game cant use all cpu cores avg can be way below 100% even if some cores're already running at 100%.

That could not be further from the truth. TW3 is CPU HEAVY game and one of the most intensive games that you can play. Especially when you reach a city like Novigrad or Oxenfurt, unless you have i7 or i9 you'll reach 100& usage easily.

[la_nague]

is that 50 in cities or in the open with not much going on?

Witcher 3 in cities etc needs lots of CPU, i think then it can drop that low with your CPU.
CPU utilization is tricky, 50% doesnt mean much.
Try changing graphic settings like shadows etc to lower, if the FPS stay low, then it might be your CPU, because a CPU bottleneck can often be diagnosed by changing settings to lower versions without gaining much FPS
