-** Fixed a client crash when switching between windowed-mode and fullscreen for {{mac|4}} and {{linux|4}} clients
+*Added a borderless window option to video settings
-** Added experimental {{code|cpu_frequency_monitoring}} convar to detect thermal throttling. If you have performance problems on Windows, add {{code|"+cpu_frequency_monitoring 2"}} to the command line to see if CPU thermal throttling is an issue. If the displayed CPU frequency percentage drops below about 80-85% then you may have a problem with your CPU slowing down due to overheating. If it drops below 50-55% then you may have a serious problem. CPU overheating can be caused by overclocking, insufficient cooling, insufficient airflow, failing or dirty fans, or other causes.
