Sub-Application + V-sync causing extreme lag.

Metal_Shadow · May 24, 2018 at 5:12 PM

Hi! I have a problem with the clickteam fusion when I use Direct3D 9 + Sub-Application + V-sync. This causes a huge FPS drop in the application.

If in disable of V-Sync the problem disappears, but I need the V-sync to solve the screen tearing in my game.

If in check (display as sprite) in Sub-Application properties the FPS normalizes. But the Sub-Application frame loses the (Anti-aliasing when resizing) effect, and I need it too. D=

Does anyone know if it is a problem of Clickteam Fusion or would it be from my PC? I posted an example .MFA in this post.

Suggestion: Turn V-sync on only when needed?

Sub-App Do you need effect or just want effect? Is there another way to display info without sub-app?

[MENTION=8114]Metal_Shadow[/MENTION]: The app runs at 60 FPS with Vsync on (tested with Fraps); your counter shows 30 FPS tho, for a reason I don't understand. Did not find any mistake here. Maybe try to grab the FR from the main window?

I don't suppose this has anything to do with it, but just be aware that having the debugger open (like in the first screenshot) absolutely kills performance, so always make sure you disable it if you're going to measure framerate.
