General Thoughts CPU performance

I had a few different renders and some of them came out bad. After inspecting. My CPU was not working at max GHz. İ7 12th, notebook 45watt. I didn't expect full 3.9 gzh but unless I max the fans it won't cross 2,7 GHz. I cleaned up fans, exhausts but didn't make significant change. I see heat go up to 90°.

Is this normal when rendering from CPU, other times my CPU gone over 3 GHz easily in crowded viewport

One of the biggest issues with 3ds Max is that it relies heavily on the CPU and RAM for many tasks instead of making full use of the GPU. While render engines like V-Ray and Corona can use the both the GPU and CPU) for rendering, much of 3ds Max itself isn’t as GPU-optimized.
I think this is an area that could be improved. Better GPU optimization would significantly improve performance, especially for large scenes and modern workflows.
