I managed to fix it and it was a very small change that did the trick.
I ran the RuneScape NXT Client as admin.
Never thought to try it previously.
]]>Alt1 detects the linked window, and when I turn on "Draw pixel detection debug data on the screen" it puts a red box around the game and a red rectangle around my right clicks in game.
]]>The screenshot you sent does have the correct render settings to work.
]]>My NVIDIA Settings are all set to "Application-controlled"
I've tried with and without "Override Runescape DPI scaling detection"
and I've tried running as admin just to see if that would fix it.
If I make RuneScape run in compatibility mode and use DirectX I can capture just fine but I end up with BSOD due to some unfixed issues with my graphic drivers and windows 10, the only way to solve this is rolling back the drivers which then causes issues in other games.
Basically I need to figure out why OpenGL Capture won't work.
I've attached a screenshot of my ingame ui and graphics settings, if anything else is needed just ask and I'll get it asap.
