Is the GTX 780 bottlenecking the 9900K?

Featured Replies

Hello,

I have recently build a new computer.

9900K
32GB ram
2 SSD 1TB/512GB
GTX 780.

I have noticed that the GPU sits on 100% all the time and the CPU is around 12%. And it is devided over 2 cores (0-2).
So I wonder if the GTX 780 is the bottleneck here?
The values stay there, even if I set everything on low.
FPS is between 25-50. Set to 60. Where I am not unsatisfied about this.

 

Thanks ahead,

RobB

What are you doing to drive the GPU to 100%?

Are you maxing out VRAM usage?

Start by reducing settings to get the GPU usage down!

Yeah that's an old card.  You're pretty unbalanced at the moment.  Try to find a GTX 1070 Ti or a straight 1080 and you'll notice a big difference.

Absolutely.

@Bert Pieke Absolutely nothing.
All settings minimal (sliders to the left).
No AA or traffic.
And weather I did put the sliders of the world to the right not even the fps changed. CPU usage and FPS stayed the same.
FPS only dropped after I added 10% traffic.
Tessalation was set to 0.

@ryanbatcund @Luke  Thanks for the advice.
Fastest in the shops around here is the 1050, or jump the 1660 or even the 208/2070.

9900k 2070 would be a nice combo

Would the gtx 2080 or 2080 TI add something? I am considering either of the 2.
I even saw some tests with SLI.
I am using 3x 24" monitors. And I am not sure if I like that.

Thanks
RobB

the perfect combo with 9900k is single 2080TI, one more card dont give mutch 

If you run P3D with high settings a single 2080TI handle +5.5ghz cpu , i have some 2080TI tested SLI think i not have cpu for it i stuck with single card.

when i run 2x1080TI SLI there its  a benefit over single card , but not much with the 2080TI

Then I will buy the 2080TI.
Thank you for the Advice.

Rob,

Try this site...I use it for trying different combinations of hardware before I "dream" of my new system.....http://thebottlenecker.com/#home

Interesting results often times.

You're going to notice a big difference (of course it will cost a bit ha)

after 15 minutes of flight I am getting Card 780 stopped working.
Is that what you meant by:"to few memory"?

 

Thanks,

Run GPU-Z (freeware) alongside your flightsim.. it allows you to track both VRAM and GPU usage numbers.. and temperature...

(Sensors tab..)

Will download it and run it.
Thanks for the effort.

Considering all the stories here, how much would I gain with the TI over the non-ti 2080?
I ask that because the pricetag is nearly 50% difference.
If it is 30 to 33 fps or 50 to 55 fps I might even consider the non ti. But later regret it ;-).

There is a chance not taking the 3x 24, but going back to 1x 24" due to the stretched images on the 2 outer monitors.  Which looks ugly, but I could get used to.

Thanks for your thoughts.
