So even if you play 100 hours of ARMA3 a month, it will have little effect. 2 months of High Performance profile resulted in a $5 difference in electricity bill. If you're having issues running CPU at max speed, it will happen during heavy load, regardless of you forcing it to max speed constantly or not.įrom a power consumption point of view, I actually did the test once. How can C-states/EIST regulate CPU clock speeds when your Windows setting forces your CPU to constantly run at max speed? I would like to hear that explanation.Ī properly built and set-up system will have no problems running the CPU at max speed 24/7 for 5 years. You're right, that's how your system should react - but with ARMA/BI, you never know. The power delivery/regulation of todays motherboards and CPUs is so dynamic and sophisticated that forcing a machine to run full tilt 24/7 would simply be out of paranoia and a waste a whole lot of power in the meantime. 8-10 watts power draw while dicking around on the desktop, and instant full speed during ems the best of both worlds. Also, if anyone cares to know, I have all C-states and EIST enabled (CPU idles 800mhz) and the instant I run Arma it clocks to max and stays there. Whether the difference in Arma performance is noticeable or not by changing power profiles and priority in Windows is mainly besides the point here because it doesn't even achieve what you are after. If you want to ensure your chip runs at peak frequency at all times you must go through some BIOS/UEFI settings to disable C-states/EIST, raise or remove power and current limiters and have proper cooling to keep the chip form throttling itself. Even then, setting your power profile and priority does not keep it from doing so. Modern chips are constantly changing clock speed across cores independently in a time scale which may as well be called "instant". I'm missing the point here as to how this will increase performance. If you actually follow through, let me know if you saw a performance improvement or not. Verify you've done correctly by making sure Process Lasso changes to Bitsum Highest Performance while ARMA is running and back to Balanced when it's not. You can also add arma3.exe to a list of application power profiles Make sure your 3 Gaming mode settings are enabled Right click arma3.exe and make sure you 'Classify as a game' and set the Priority class -> Always -> High Load ARMA and then alt+tab to access Process Lasso The software has a 30-days free trial but these features are going to remain available even after the time runs out It's done automatically on my system with Process Lasso by Bitsum and what's even better - is that the software changes those settings back off once arma3.exe process is terminated. What Process Lasso does is just AUTOMATE THE PROCESS, so you don't have to do it manually every time. This setting unparks all your cores and sets the CPU frequency to it's maximum possible. So to solve this, I set arma3.exe process to High priority and whenever arma3.exe is running, I set the windows Power Profile to High Performance. It works, but wouldn't you rather be sitting there, revving the engine in anticipation, already? To give it a real-world example, it's like having a race car sit on the Start-line with its engine turned off, waiting for the light to change and start it immediately as the light turns green. This means your CPU has to react to the request and then raise its clockspeed. With these settings, your CPU cores might be parked for power savings and only unparked once the game is demanding more processing power. From my own testing, I managed to raise my game's performance by making sure my CPU is giving its 100% while playing ARMA3.īy default, running arma3.exe in Normal priority and Windows Power Profile set to Balanced.
