OpenGL på vista

Man plejer at hente det software der nu skal bruges til ens grafikkort... :)

According to a Microsoft blog, there are three choices for OpenGL implementation on Vista. An application can use the default implementation, which translates OpenGL calls into the Direct3D API and is frozen at OpenGL version 1.4, or an application can use an Installable Client Driver (ICD), which comes in two flavors: legacy and Vista-compatible. A legacy ICD, the kind already provided by independent hardware vendors targeting Windows XP, will disable the Desktop Window Manager, noticeably degrading user experience under Windows Aero. A Vista-compatible ICD takes advantage of a new API, and will be fully compatible with the Desktop Window Manager.
At least two primary vendors, ATI and NVIDIA, are expected to provide full Vista-compatible ICDs in the near future.
However, hardware overlay is not supported, because it is considered as an obsolete feature in Vista. ATI and NVIDIA strongly recommend using compositing desktop/FBOs for same functionality.

Nå, jeg lægger et svar. Ovenstående betyder blot at du må vente til din gfx kort producent laver en passende driver som håndterer OpenGL, og så satse på at Counterstrike ikke har brug for højere end OpenGL 1.4.
