Hello,
I'm not a performance optimisation geek, however I've observed something in VAM what at the first sight is not logical.
I'm running VAM in desktop mode on an a little bit outdated laptop (i5-7300HQ, 8 GB, GTX1050), so I don't expect high performance. I've noticed that disabling the mirrors in graphic setting improves the fps a lot, from 10-15 to acceptable 30 (high graphic settings). However, the increase is only short, after few minutes it drops down to 10 fps, even if I leave the VAM unattendend and change nothing. I've found out that with mirrors off my CPU usage reaches 70-80%, temperature rises quickly to 90-95 C and automatic downclocking is applied to save the CPU. However - and that's a surprise to me - switching the mirrors back on results in the CPU usage drop to 30-40 %. Of course fps drops again, CPU cools down and reverts to the standard 2,5 GHz.

Is it an expected behaviour, or something is wrong?
Why the CPU uses only 30-40% when mirrors on - regardless of the scene, animations ect. Why VAM doesn't put more workload on CPU to improve the fps at least a bit?
On the other hand, when mirrors are off, why VAM doesn't limit the fps to put less workload on CPU to avoid overheating? Finally, mirrors on is a more demanding setting, isn't it? So why overheating takes place on less demanding settings and doesn't happen with more demanding?
I'm not sure if constant 70-80% of CPU usage schould really overheat it, perhaps there is something wrong with my laptop?
Right now the only option for me to get a playable VAM is to.... frequently switching the mirrors on to cool the CPU. Where is the logic?
Thanks for any advice.
