Compatibility Report

  • Names of the games with compatibility issue: Lego Racers, Trackmania Nations & United Forever, Crazy Taxi, Grand Theft Auto III, Vice City, San Andreas, maybe others
  • Steam AppID of the game: n/a because Non-Steam games

System Information

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

LT & RT (the left & right triggers) of both a DirectInput & a XInput gamepads work not on these 7 games, I can not bind these 2 keys.
But they work on Windows 11.
This issue seems to be on old games, e.g. recent games as BioShock 2, GTA V, THE FINALS there is not this issue.

This issue looks like https://github.com/ValveSoftware/halflife/issues/3789 .

Reproduction

Add a Non-Steam Game the .exe of the 7 games
PLAY
Try to bind LT & RT.
