In UN 4 I have my GPU always at 45/46 percent also in MSI Kombustor and many other stress test.
GPU: Quadro FX 5800 with latest nVidia driver, 342.01
CPU’s: dual Xeon E5420 2,5 GHz not overclocked.
Main: Asus DSEB-DG - 771 socket
RAM: 8 Kingston, 16Gbytes FB-DDR 2, PC2-5300 at DRAMM Frequency 333
DirectX supported by SK Video is 11 (10_1)
Every settings in nVidia Control Panels are ok.
Unreal Engine Ver. is 4.14.3 - more recent versions have issues, above all on texture streaming (UE crash).
I know that the Hardware is very old but this is my only possibility at this moment (budget troubles).
OS: Windows 10 pro 22H2 Updated.
I’m looking to know if it possible to know where is my bottleneck and how resolve it in order to reach the GPU use at 90 percent.
Many thanks to all, and sorry for my english

You are probably CPU bound. Your CPU cannot calculate at the speed needed to saturate your GPU. There is no way around this type of problem. It’s called a bottleneck for a reason.
The only way to get full performance out of your graphics card is to either reduce the amount of needed CPU calculations or upgrade your processor to a faster one.
Your ram is also only DDR-2 so a faster CPU will probably still be waiting for the ram to serve the needed information.
Hey 3dRaven and thanks for your fast answer.
Ok you have confirmed my thought. But I have a question for you. How can I reduce the needed CPU calculation?
Check for background programs that might be eating up CPU cycles.
Check CPU usage for processes in the task manager. Perhaps a background program is taking up needed resources. (sort by CPU)
Try to give as much of the cpu to Unreal as you can. Turn off any background browsers, music players, instant messaging apps etc.
You also have to check that your in game logic is well optimized. Complex operations linked to on tick can cause performance problems.
If you are hitting RAM limits then you can also try increasing your page file size.
