Thank you for your reply.
I am currently using Intel Arc driver 32.0.101.8864 because of this issue.
The problem started with driver 32.0.101.8974 and still occurs with the latest driver, 32.0.101.8991.
With these drivers, Turzx 3.5-inch cannot detect GPU usage, while GPU temperature, GPU clock and VRAM usage are still detected correctly.
HWiNFO, GPU-Z and AIDA64 can detect GPU usage correctly with the same drivers.
I am using 32.0.101.8864 as a workaround because GPU usage can be detected correctly with this driver.
I hope your team can look into this issue.
