Forgaming I don't think it'll matter either way. MCE on will probably be a few percent faster though. Technically if you wanted to change bios settings to make it as fast as possible in gaming (and only gaming), disabling hyper-threading will give you ~1-3% in some games and disabling the ecores will give you ~2-4% in some games. Yes the clock of the cpu changes when is requested more performance from the cpu, however that will continue to work even with speed shift disabled, because speed step and turbo boost are enabled. The problem is that HWiNFO64 utility and Quick CPU say that is not using speed shift in windows 11, but in windows 10 say that the Performance Turningoff Virtual Machine Platform (VMP) Select Start , enter 'Windows features' in the search box, and select Turn Windows features on or off from the list of results. In the Windows Features window that just opened, find and unselect Virtual Machine Platform . Select OK. You might need to restart your device. Pressthe Windows key, type " Edit power plan ", and open the app with the same name. Click on Change advanced power settings. Select Processor power management: Processor performance boost mode. Change the option to Disabled. You don't need to reboot your computer, the change is applied immediately. Thei5-4690k is a 3.5GHz CPU with a turbo boost up to 3.9GHz. HWInfo showed that all 4 cores on my CPU averaged very close to that 3.9GHz for the 2 hour session. The cores were averaging about 80% use and temperatures averaged in the mid 50s on each core. Asfar as I know gaming performance wont decrease at all, maybe only for some really cpu intensive games during the first few minutes. But after the temps have raised, it wont hit turbo speeds anymore anyways. It'll probably run under base clock with the thermals of the xps. For normal use you won't notice much of a difference either. Thestock all core turbo clock on the 9900K is 4.7GHz, enabling multi-core enhancement will increase that to 5GHz. 16 Start with 49x or 50x, and you can just type it in on most motherboards. 2vHn.

should i disable turbo boost for gaming
