Right now i know some games run in OpenGL (Quake series, Doom3) and some in D3D (FarCry) and untill recently i didnt care what it run in aslong as it played well
BUT! i've just read that OpenGL renders alot faster than D3D and i remembered that in the options of Counter-Strike it lets u choose to run the game in either.
Now i've Always had it set to D3D so set it to OpenGL and went for a few timerefresh tests.
I get at LEAST 90fps MORE with OpenGL everytime. No matter what the map (aztec, dust, inferno etc).
Also the colours seem richer
So is this a one off? Half-Life is the only game i have (i think) that gives u a choice so i can't try it out on another game.
OR! is it my video card? As i've also heard that nVidia's are the better OpenGL performer wheres ATi are king of D3D?
P.S Back in the early days i remember when OpenGL was the new cool kid on the block and made D3D gaming look naff!
As Anyone who fired up GL Quake for the first time will testfy!!
