X3D Gaming Mode

Building out a new rig and I found a BIOS setting called “X3D Gaming Mode”

Curious if anyone has benchmarks or other performance data for MSFS (both versions preferably) comparing having that enabled or disabled.

Thanks!

Interesting. I wonder what it does.

Windows Game Mode favors X3D cores when it detects a game like this sim.
And the Windows Power Plan you use affects core parking, if I’m not mistaken.

I have a 7950X3D. I turn Game Mode off, and set the system to use Ultimate Power Plan. I use Process Lasso to assign the sim’s .exe process (and only that one) to the X3D cores, and Bitsum’s other app, called ‘Core Park’ to disable core parking.

I’ve done a lot of testing, and found that gives me the best results with this CPU. I bought the 7950X3D when I bought FS2024, and don’t use FS2020 any more, so I don’t have any comparative data for the latter.

I’ve got a 7900X3D myself. I guess I can just try turning it off and on when I’ve got things set up and see what happens.

I highly recommend testing the perfomance as you change those variables (one at a time) using the free test software CapFrameX.

I’ve got a 7800x3d and have it enabled but don’t see much difference either way. It says in AMD write up that it works better in some games and not others so checking it on your own rig is the way to go.

What’s the motherboard manufacture? AMD added some tweaks to their AGESA v1.2.0.2a (which is embedded in your bios by the motherboard manufacturers) to modify certain bios parameters to improve performance of their 9000 series x3d chips. Some manufacturers like Gigabyte have extended those benefits to the 7000 series chips also.

Each motherboard vendor implemented those tweaks a little differently so it would be best to check on your motherboard vendors web site.

My motherboard manufacturer (Asrock) only implemented the performance enhancements for the 9000 series x3d cpu’s so I don’t have any direct experience with it since I have a 7000 series x3d.

Don’t use it. It turns off your logical cores for physical ones. Made my 7900X3D worse.

AFAIK all it does is disable SMT (ie hyperthreading, so you will have as many threads as physical cores, instead of twice as many threads) and it disables one core or something. Wouldn’t recommend it unless you have many cores to spare.
