Example 12 TerrainRendering 2 observations

Post by Woozley »

I noticed on my vista system on the terrainrendering example I get ~220 fps using d3d9 but over 300 fps using opengl. Wow I thought opengl was slowed by vista. Is this an engine or implementation issue or am I just lucky :) ?

I also noticed if you look up there is a 'big flat plate' in the sky(box) roof (renderer independant) - is this how the sky is supposed to look ? Not being critical, just trying to learn irr.

If you have installed your latest vendor video drivers (Nvidia, ATi) then the performance of OpenGL will be the normal. If you haven't then OpenGL will be greatly slowed because its a wrapper for DX.
