![]() However, again, we can’t say whether any specific adjustment will work to achieve your goal. CPU affinity: A setting that determines which CPU cores a process can run on, allowing you to optimize the CPU usage and performance of specific applications. To accomplish this, it uses a staggered CPU affinity so that only distinct physical CPU cores are available to target processes. ![]() A better strategy might be to constrain the CPU affinity of a problematic background process, or constrain the CPU affinity of a game to a specific set of CPU cores. Note that the overall CPU usage is just fine (less than 30 most of the time), but in Resource Monitor, same as the Process Lasso, it's obvious that that most of the load is on CPU0 and the others are almost free. I've sorted all with respect to their CPU usage. In most cases, it is best to give the system leeway to schedule threads on whatever CPU cores it deems appropriate. PS: These are screenshots that show the more familiar Task Manager and Resource Monitor. For instance, trying to micro-manage all process CPU affinities probably isn’t a good strategy - though it might work. We advise to precisely target process settings and limit the number of rules. Performance Mode is also immediately useful for systems that don’t already have tuned power profiles, or where automatic switching to a higher performance power profile is desirable. Therefore, the general guidance is to simply install Process Lasso and use its ProBalance. When general optimizations are known and possible, algorithms like ProBalance were created. The OS will try to abide by a CPU Set, but has discretion to schedule outside the Set. Instead of a hard contract, they are a suggestion of preferred CPU cores. ![]() As an application developer, we only strive to enable users full control over their running processes. If you are an advanced user you will be happy to know that Process Lasso can be used to change the priority of processes, the CPU affinity (Core selection). This exciting release of Process Lasso v10.4 adds CPU Sets and Intel 12 th Gen (Alder Lake) support CPU Sets CPU Sets, a native Windows feature, are a ‘softer’ form of CPU Affinities. We don’t know whether specific adjustments to CPU affinity or other settings will achieve your goals. ![]()
