v4.37 of Open GL. Instructions are inside the zip.

Latest Version of OpenGl

I would recommend everyone to update to v469 since it makes the game run a lot more smoothly and you can now run the game on 240hz in case you have that and other tweaks to the game. like raw input. It will make the speedrunso much better! 
Just press this and you will be redirected to the page and there's a tutorial how to update the game.

Patch 469

If your game doesn't run smoothly and/or feels clunky try using these settings, might help you out.

Extract the files onto your UT System folder (ex: C:\Unrealtournament\System), make backups of your existing files if need be.
