Adjusting the affinity of a program to use the core does not typically lead to future Windows issues.
Adjusting the affinity of a program to use the core does not typically lead to future Windows issues.
I applied the Set affinity tool in Windows Task Manager to control browser CPU usage. I wondered if I should use the same setting for my games. Would running them on half cores make the laptop cooler and extend its life? It worked without problems. However, adjusting OBS studio’s affinity to one thread caused recording delays. There might be risks if CPU overloads occur, potentially harming the processor. This approach seems reasonable but should be used cautiously.
Several factors need attention here. The main idea is that adjusting affinity can improve edge cases but isn’t essential for everyday use. For instance, running a game on half the cores might cause the CPU to overheat more, even though it seems counterintuitive. Modern CPUs, especially in laptops with tight cooling, hit power limits that slow each core and reduce efficiency. With half the cores active, each one gets double the power allowance and can perform better. Even when idle, active cores may still run hotter. This approach worked on older systems where boost speeds weren’t as distinct from base speeds. You should give the CPU enough capacity to meet your needs, but avoid manual affinity settings unless you have a precise performance goal. Keep track of which tasks go to which cores to prevent overloading any single one.
