Windows 3.1 / MS-DOS Lag on new ASUS TUF Gaming laptop.

Yes, I think it does have the correct information, all my VMs are MS-DOS and Windows 3.1. Off-topic? that was a mistake. Badly written.

OK, thanks for the information. Please don't read and respond to only the last line in a post. Several posts above had multiple questions that you've missed. Please go back and read/respond to them.

Even if VT and PAE/NX are disabled.

Neither DOS nor Win3.1 knows how to use PAE/NX.

And you don't have the option in VirtualBox to disable VT-x. You DO have the option to disable "Nested VT-x/AMD-v", but neither DOS nor Win3.1 understands that CPU feature either, so either way it does nothing.

Instead of randomly flipping irrelevant switches, tell us what are you trying to achieve?

If the goal is gaming on DOS or Windows 3.1, VirtualBox is possibly not a good choice since no graphics acceleration is provided for unsupported guests.

My goal is to solve this problem because Nested paging causes this. Disabling VT, PAE, nested paging, and 3D graphics does help but not without losing performance.

PLease read all posts since you posted last, not only the last post. You're missing lots of questions that might help us diagnose this.

Locking this topic for a day so you can read back what you've missed.

You need to use power.exe , dosidle or some other DOS power saving utility to prevent DOS from always using 100% CPU.

You can do "help power.exe" to read the manpage, or just search around.
