I had it too on Win 7 x64. Hope it gets fixed in this version.

That's a known problem on Windows 8. See here:

http://support.microsoft.com/kb/2908279 (explanation is beneath "Let me fix it myself").

If you don't want to do this stuff manually, you can try my fix. Download this ZIP and extract it:

https://tron.hirnschwund.net/patches/tron20-mousefix.zip

Make a right-click on the tron20-mousefix.bat and select "Run as administrator". It should work now.

Note: If you haven't installed TRON to the C: drive, edit the tron.reg first.

Fails to do it running as Admin or not, it just says, "Cannot import tron.reg: Error opening the file. There may be a disk or file system error."

Oh good god, I just found out the problem and fixed it, it was the polling rate of my mouse, I'm using the Redragon Mammoth and had the polling rate set to 1000hz, I set it to 250hz and now the mouse is fine ingame.

It still aims diagonally though

If the manual steps on the Microsoft website or my fix don't work, I'm afraid I can't help you. Mouse jumpiness is a known problem with Lithtech engine games on Win 8.1 - the fix seems to work most of the time, but as far as I can tell it depends on the mouse driver, too.

I'm running Windows 7 x64 and no fancy drivers. Funny thing, it worked fine at first but then I had to reinstall the game and the mouse was all jumpy and moved diagonally.

The fix is meant for Windows 8.1 - the option "NoDTToDITMouseBatch" is only available there (and on the Windows 10 preview). It won't do anything on Windows 7.

On Windows 7 turning off mouse acceleration in the control panel usually works.

It's idiotic that Microsoft hasn't added the mouse fix as an option you can check, in the Compatibility tab for Windows 8.1. It's still not there yet in Windows 10, either.

Their "solution" was to have 8.1 recognize certain games, and automatically apply the fix. Which is swell and all, until you play a game that isn't on the list of recognized games.

Lower your mouse polling rate, this seemed to work for me... But it still was a tiny bit diagonal, but barely.

Yes, the fix does only add registry keys for a bunch of games. I believe the article even states that the list is "constantly updated", but they don't give a damn, like usual. ;)

At least they give you instructions on how to add a key yourself.

An interesting fact is that even on Linux with wine people have these kind of mouse problems. But not all of them. It really seems to depend on the particular type of mouse. I have a Logitech mouse with dual lasers, the game does not seem to like them that much. ;-)

The fix from Le BDX777 #MGTOW works for me, too.
