Hi there, is it your first core that is maxing out? If so there is a trick us music producers do that can alleviate that and spread the workload across the other cores, all you have to do is bring up the task manager, right click the Affinity software, choose GO TO DETAILS, look for Photo.exe and right click it choose SET AFFINITY, disable core 0 which is your first core, this is the core that Windows uses mainly, when this core is overloaded it can cause a crash. It will revert back to normal after you restart Affinity, if you are still experiencing problems then follow the same steps as above but give Affinity a lower priority.
