Troubleshooting
Mouse Lag/Acceleration
Some users report that the mouse feels laggy and looking around feels unnatural. Some have attributed this to an implementation of mouse acceleration, however Eidos developer Jimo has stated that there is "no mouse smoothing applied in DXHR".
The problem may simply be input lag which is usually related to V-Sync. Disabling V-Sync seems to fix input lag for most users.
Other users, under the impression that the game implemented mouse smoothing, seem to have found a registry setting that modifies mouse behavior and have had some success with editing it to fix mouse lag. Use these steps (listed below) to edit this specific registry setting (Be sure to back up your registry before making any changes):
- Navigate to "HKEY_CURRENT_USER\Software\Eidos\Deus Ex: HR"
- change the value of g_debugFreeLookSpeedScalingRatio_Pitch from 6e 00 00 00 to 00 00 00 00
- change the value of g_debugFreeLookSpeedScalingRatio_Yaw from 86 00 00 00 to 00 00 00 00
- re-adjust your mouse speed in game, no acceleration
Tutorial Crash
If your game crashes when a tutorial pops up and only shows black, go into the game options and disable tutorials.
