AMD + CS 1.6 Compatibility Profile Context

[Krexc]

Is it normal for the game to start in this Compatibility Profile Context on Windows 10? or did my windows tweak and cleaning cause that compatible mode, is there a better mode?
The reason is that my AMD Adrenalin settings aren't working properly. The 3D application settings are not being applied to the game; only display settings seem to work. For example, even if I disable V-Sync globally and specifically for the game, I can still control it ingame using the gl_vsync command, which wasn't the case before. Similarly, frame rate capping and texture quality/performance tweaks have no effect no matter what I change in the software, the game remains exactly the same.

Half-Life still uses OpenGL 2.1 even after the 25th anniversary update. Only apps that use OpenGL 3.1 or later may opt into Core Profile; anything that requests an older OpenGL context will always use Compatibility.

Note that Mesa drivers are limited to OpenGL 3.0 in Compatibility. Only proprietary AMD/NVIDIA drivers support higher versions in Compatibility contexts.

Regardless, I don't think using a Compatibility context causes issues with driver forcing V-Sync or framerate caps.
