user.cfg trick lower CPU usage doesn't work - hurts FPS on Intel E-Cores

I had a person I know test it with their 9800x3D and it had similar negative impact to my 14900k test.

4% drop on average FPS
15% drop on 1% low FPS
16% drop on 0.1% low FPS

Any "benefit" to CPU load or power or heat is because these commands have a negative impact on the game's ability to run properly. It will also make the game stutter and dip more & the frametimes will be worse and with more variation frame to frame. That much drop on the 1% and 0.1% is something that will make the game less smooth and worse feeling.

Making the game run worse isn't a solution to anything. CPU's are designed to run at full usage and most have a thermal throttle temp of 95c and higher.

Usage might be a problem if you're pinned at 95% to 100% constantly while the GPU isn't, causing bottlenecking. Heat is a problem if it's in the 90's, and it's something you might want to look at improving when it's above 70c in-game. Almost all situations where the CPU usage/heat is pinned or throttling there are solutions to try before you take the drastic step of killing the game's ability to run.

Things that might be able to be done to improve the situation instead of using these broken commands that destroy your 1% and 0.1% lows:

• Use bios commands to reduce your boost clocks or set power limits or if you are comfortable with tweaking, undervolting.
• Check that your memory is being run at correct speeds, for most people this will mean double checking it has XMP enabled (or EXPO on certain AMD boards).
• Reduce game settings or resolution or use DLSS if you have it available but aren't using it.
• Clean your case and the case/gpu fans, if you haven't done this for a while your fans and radiators might be clogged with dust.
• Consider upgrading your CPU cooler.
• Consider repasting the thermal paste on your CPU if it's older than 1 year. I use thermalgrizzly phasesheet, but have also got good results from mastergel maker, thermal grizzly's kryonaut extreme and noctua paste.
• Check if your case can add more fans for intake or exhaust.
• Find out if your case fans are low speed (1200 rpm and lower) and could be upgraded, or perhaps the case itself might be a poor performer (eg it's a glass front style case) choking airflow.
• If you are on a laptop you might want to get a laptop cooler like a Llano or IETS.
• If you have 4 sticks of ram in your motherboard this might impact performance, especially if it's on a DDR5 system. Consider consolidating into a two stick solution with a set of ram that matches your capacity needs and is on the QVL with a good XMP speed.
• Older CPU's may benefit from an upgrade within the same socket. For example, if you had an Intel 9th Gen i5 with 4 or 6 cores, you might be able to upgrade to a 9700k or 9900k with 8 cores. Most AMD CPU's have similar upgrade paths, like upgrading from a Ryzen 5 with 6 cores to Ryzen 7 in the same Zen generation but with 8 cores.
• Disable the in-game frame cap and any GPU control panel cap (eg, Nvidia control panel) and if you use afterburner with RTSS, use RTSS Async frame-cap. There's a problem with the ingame or Nvidia control panel frame cap that causes increases frametimes, with small impacts on Average FPS, and larger impacts on the 1% and 0.1% lows. My testing showed the 0.1% FPS increasing from 94 up to 107 with RTSS capping. This may allow the game to utilise the CPU more efficiently, reducing load.
