a750 usege is too low

[BigfeetCat]

The usege is only 20~30% when playing Death Stranding, 40~50% usege when playing Nakara Bladepoint. In basically all games, the graphics card power is only about 100w or less.

CPU Bottleneck 

Hey, make sure if:

1- Resizable Bar is ENABLED
2- You're using the latest WHQL drivers with Windows 10 20H2 or NEWER
3- Your PSU is enough for this GPU (650W+)

Looking at your system specs, your CPU is a i3 10105F, this CPU will surely bottleneck the A750, as even a Ryzen 3600/i5 10400 will sometimes (ARC have a lot of driver overhead, so it uses a lot of 1-2 cores on the CPU).  I would recommend upgrading to a 11400F or better (H510 should be able to handle it with updated BIOS).

Hello BigfeetCat,

Thank you for posting on the Intel️® communities. We would be more than glad to help you.

The recommendation shared in the thread by AjrAlves are correct, and you should make sure that Resizable Bar is enabled. However, it is important to mention that we recommend using a Minimum 600W power supply with two PCIe power connectors – 1x8-pin & 1x6-pin; but it is always recommended to have a PSU with a higher capacity.

As for the processor, sometimes the CPU can restrain the graphics adapter from running at its full potential. However, to discard the possibility, check if the CPU is under heavy load by checking the CPU usage.

For testing purposes, try the Display Driver Uninstaller. Check How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver for instructions. Once you run the tool, you should install the latest driver from the Intel driver, 31.0.101.464. The DDU tool will eliminate all drivers and leftover files from previous driver versions, and we can discard that there are driver leftovers causing your issue.

Hello BigfeetCat,

We have not heard back from you, so we will close this thread. Our recommendation is to try using the Display Driver Uninstaller to eliminate all driver residues and discard that the issue is being caused by previous drivers' leftovers.

If you need additional information, submit a new question since this thread will no longer be monitored.

Best regards.
