Rendering problem on Intel Core i9 12900KF CPU

[Three_D]

Hello 

We've changed our company CPU to intel Core i9 12900KF (16C ,24T) and the th PC is used mainly for 3DS MAX and Corona renderer . the problem is while rendering the task manager shows that only 8 threads are used from the 24 , and the overall usage at 40%.

we've updated the Bios and all drivers

the OS is windows 10

64G RAM 

Thanks

Unless I don't understand your query, you are talking about graphics rendering operations. These kinds of operations are actually going to be performed mostly by the iGFX engine. It's somewhat interesting that it is taking 8 threads to support the feed of these operations in to and out of the iGFX engine (I would have guessed less).

thanks for the feedback ,

I should have noted that Corona for 3DSMAX   depend heavily on CPU thread count and normally takes all the processer's power

also i've tried to benchmark using cinabench it used 100% of the CPU .

thanks
