As indicated, this problem is easily visible from the Task Manager itself, where only the physical but not logical cores (threads) of the CPU are used, a problem that does not appear when the processor is from Intel. This is because Intel C ++ compiler has been used, leading to a performance loss of up to 20 percent. As an example, users who have tried the solution to the problem have experienced great performance improvement of more than 10 FPS in CPUs with 6 or more cores.
