We can help, but we need to know more! Do this:

• Click the Windows Start button and search for “FBX”. It should find the “FBX Game Recorder” folder.
• Open it and select the ‘Send a Problem Report’ item

We’ll need to see log files from your PC to figure out what’s going wrong. 

• Reproduce the problem
• Go to the Support tab (restart FBX if necessary)
• Send us a report

If you can’t see the overlay, it means FBX can’t record that game.

FBX has been coded to be compatible with a wider range of games than other recorders, but it can be blocked by anti-cheat software or some older games may use technology that it can’t record. We can help:

• Reproduce the problem
• Go to the Support tab and send a report

Select the right encoder – make sure you have a hardware encoder selected if one is available. 
Don’t set a higher frame rate than you need – recording at a higher FPS will waste processing power.
Reduce the resolution/quality of the recording – select something other than ‘Original’ for the resolution or reduce the quality setting.
Close unused apps running in the background – they may be competing for system resources (CPU / memory).

Tencent Gaming Buddy has a number of different Rendering settings and whilst any of the DirectX or OpenGL options should be compatible with FBX, we’ve found they can give inconsistent results.

Go to Settings > Engine in Tencent and select “OpenGL+” – this option seems to work best.
