Does 'max vertices in vertex array' matter?

Hi there,

I recently noticed that in System Info report the same machine generated very different max vertices in vertex array when it runs under different OSs. Under Windows 11, the max vertices in vertex array is 2^20, but the number becomes 3000 when I booted into Ubuntu (22.04.1). OpenGL version is 4.6 in both OSs.

I’m wondering why these numbers are different. Is it because the driver of graphics card (Radeon RX 6500 XT)? Does the number mean anything regarding performance?

More importantly, does it mean that PsychoPy performs worse under Ubuntu that Windows in this case?
