OBS Studio Game Capture not working on certain games?

[awesometf2player]

My PC is a Windows 11 64bit.
I use OBS 64bit version 29.1.3.

OBS Studio Game Capture just shows a black screen trying to capture ROBLOX:

But...

It seems to work with TF2:

Solutions I tried:

• Ran it with Admin permissions.
• Disabled HDR
• Updated my drivers.
• Set its Graphics Settings to High performance or Power saving.
• Ran it with compatibility mode in Windows 8 or 7

Nothing seemed to work.
I think ROBLOX's anti-cheat Byfron is denying capture.

Have you tried running OBS Studio as administrator? Some games run as administrator for their "anti-cheat" provisions to work.

Rule of thumb: If ROBLOX throws up a UAC prompt when you first start it (miHoYo/HoyoVerse games are other examples of same, e.g. Genshin Impact, Honkai: Star Rail), that's your cue to start OBS Studio as administrator.
