Yes, I can make. Can user itch understand and make ? That reason for write message 

If the user uses pure Debian, then I think he will definitely be able to

Good luck with the engine updates Guva, seems its sorted for flowCRANE, nice to see low cpu usage.

[Guva]

Well, this isn't quite a victory yet — we need to figure out why Vsync isn't enabling for @flowCRANE. Whether it's Windows 11 behavior or an initialization bug. I've uploaded two versions with the FPS display enabled, hopefully @flowCRANE will test this.

https://github.com/GuvaCode/SWGalaxian/tree/main/bin

[Scoops]

Graphics Panel Overrides
Code Order: SetConfigFlags was called after InitWindow instead of before it
Windows 11 Windowed Mode: Win 11 can be picky about frame syncing in windowed mode

anyway good luck

[flowCRANE]

SWGalaxian.exe — runs at ~2200fps and tries to murder my GPU.
SWGalaxianVsyncFPSDraw.exe — runs at 60fps but tries to boil a CPU core.

I'd like to add that the game I'm currently developing using SDL3 has no problems at all with enabling VSync, also dynamically at runtime. Everything works perfectly — in windowed mode, desktop fullscreen and exclusive fullscreen (any monitor, any resolution and any refresh rate). So I think that my CPU is not a problem here.

[Scoops]

@flowCRANE, Your Intel driver is just bypassing VSync entirely on Win 11. Going back to the SWGalaxian_fpsLock60.exe build seems like the best fix since that one was already running smoothly for you.

Hmm. Okay, thanks to everyone who helped. Maybe some kind of regression in raylib. I'll talk to Ramon Santamaria tomorrow, maybe something will be decided.

[flowCRANE]

Well, for my game, I'm using the latest version of SDL3 and the basic 2D renderer, which is created by specifying gpu as the backend name in the SDL_CreateRenderer function (internally, it uses the Direct3D 12 backend on my system by default). And I can enable and disable VSync at runtime using the SDL_SetRenderVSync function without any problems.

Given that, I don't think the Intel driver is bypassing anything—it just works as it should.

[Scoops]

That's because SDL3 defaults to Direct3D 12 on Win 11, while Raylib uses OpenGL 3.3. They use completely different driver paths, so comparing VSync between them doesn't really apply here. Guva taking it up with Ramon is definitely the best way to sort out the Raylib side!

I understand, but that doesn't apply to a situation where I create a renderer by specifying OpenGL as the target backend. When I change the following line in my game from this:

Code: Pascal  [Select][+][-]

1. Renderer.Handle := SDL_CreateRenderer(Window.Handle, 'gpu');

to this:

Code: Pascal  [Select][+][-]

1. Renderer.Handle := SDL_CreateRenderer(Window.Handle, 'opengl');
2. //                                                or 'direct3d11'
3. //                                                or 'direct3d12'
4. //                                                or 'vulkan'
5. //                                                or 'software'

the renderer is also created successfully, and there are still no issues with VSync support—I can use the SDL_SetRenderVSync function at any time during runtime, switch the vertical synchronization on and off.

Guva taking it up with Ramon is definitely the best way to sort out the Raylib side!

Sure, it's worth looking into this topic. Good luck!

[olatov]

Just one more note - while raylib defaults to GLFW (which may be the culprit of this thread) as its OpenGL backend, there are other supported backends - SDL2 and SDL3 are amongst them; yet switching the backend requires recompiling the library. I am not saying that is worth the effort for end-user (although it is not too complicated), just saying it is a valid option.

Have thank for raylib header and game. Is fun retro game.

The latest version just has a mistake

Code: Pascal  [Select][+][-]

1.   InitWindow(SCREEN_WIDTH, SCREEN_HEIGHT, 'SWGalaxian');
2.   SetConfigFlags(FLAG_VSYNC_HINT);

As SetConfigFlags sets init configuration, it has no effect after InitWindow. It has to either go before InitWindow (as it was previously), or be replaced with SetWindowState to toggle the flag after the window is created.

[paweld]

@Nimbus - thanks for the explanation.
After setting the correct order, the FPS drops to 59–60, and resource usage is indeed lower—the GPU usage is around 1.5%, and the CPU load is also lower, but still above 10%.
