I have tried with SetVSync(1) SetSyncRate(0, 0) and SetSyncRate(60, 0) but the framerate keep running below 25.0
I searched for "25" in my code but no results.

Update: Tried it on another machine, and then the framerate was perfect. So I guess my code is horribly slow.

Is there a smart way to measure how much juice each function are using?

Grab and compare time at the beginning and ending of a given process.

That said, i think vsync and set sync rate are incompatible. If you want to set a sync rate, you need to turn vsync off. Vsync on will just use the display's native refresh rate.

True! What I meant was that I had tried 'em all, hoping that one of them would give some magical fix.

So simple? Okay, gave it a try. It looks like the bottleneck is Display pixelart B.
The only thing it does is a single Swap() ... can this really be the issue?

Now I see the problem. I misunderstood loadimageresized() and ended up with a 16384x5184 pixel sprite ...

With that fixed, my framerate is now about 80. Still not super fast, though.
Checking an empty test game, I got a framerate of about 800

I display a monitor-sized sprite with transparence, and a pixelart sprite upscaled to monitor size. Maybe it just take that many resources?

by not rendering the upscaled pixelart and not rendering the hd texture I can get a framerate of 230. The rendering still looks like the bottleneck, though.
