Hello, Ladies and Guys from SFML
I'm just making a little Space Shooter game, and now it runs very slow (yesterday it didn't happen). I made the project type Console type because it's the only one that is like an empty project, actually it's not possible to create an empty project excepting you use the .Net Framework (very old), so I use .Net 8. Below I copy the Console message that appears after the slow execution of my app. I'm using SFML.Net 2.6.0, VS 2022, and Windows 10. I think the problem is brave, by what I can read.
I attach the whole project folder in .rar. It's open source, I thought in giving it for beginners learning because it's not a big game.

---------------------------------------------------------------------------------------------------------------------------------------
Warning: Detected "Microsoft Corporation GDI Generic" OpenGL implementation
The current OpenGL implementation is not hardware-accelerated
Warning: The created OpenGL context does not fully meet the settings that were requested
Requested: version = 2.0 ; depth bits = 0 ; stencil bits = 0 ; AA level = 0 ; core = false ; debug = false ; sRGB = false
Created: version = 1.1 ; depth bits = 16 ; stencil bits = 8 ; AA level = 0 ; core = false ; debug = false ; sRGB = false
Setting vertical sync not supported
OpenGL extension SGIS_texture_edge_clamp unavailable
Artifacts may occur along texture edges
Ensure that hardware acceleration is enabled if available
---------------------------------------------------------------------------------------------------------------------------------
I would appreciate any help to solve this
Thank you in advance
Pablo
PS I removed the runtimes folder from the .rar, for it to fit in limit size, you should add files csfml-graphics.dll and those in the .net8.0 folder.

Sorry for the late reply - the tab had vanished in the infinite sea of open tabs ;D

This error means what it says, that it failed to find a proper OpenGL implementation and has fallen back to the most basic software renderer that Windows provides.

It looks like you may have uninstalled your GPU driver.
