Again, using 3dAnalyze you can test this. It is capable of forcing a card to use only FP16 shaders no matter what is requested. You'll see no image quality difference doing that - just a HUGE performance boost. Why? Well, because while FP16 is all that Half-Life 2 *needs*, if they let the GeForce FX cards do THAT, they might have been competitive! So, instead, they forced FP24 (unneeded), which caused the GF-FX cards to render the DX9 mode in FP32 all the time. With the obvious associated performance hit. |
