I use Intel Celeron 1005M that have 2 core and windows 10. When FDM running, i see that my cpu usage always max at 51% from task manager. Then i open resource monitor > CPU tab, when cpu usage at 51% one of the core is at 100% and another one at 0-1%. But when FDM doesnt running, my cpu usage can goes to 100%.

anyone can help? maybe there are a setting inside FDM to stop that from happening?

Hello,
Please update to the latest version of FDM.
