Video Settings

[Rudski]

I got a couple of questions and would like to know what these setting do/change.

In openGL whats Force S3TC v3 compression?


When it comes to Buffer Flipping whats better block transfer or Page flipping?


And how many frames rendered ahead is best? Default is 2.(OpenGl)

with DirectX its 3 frames Default are rendered ahead.

whats better?

Im looking for the most 3Dmark points i can get so which ones are better for speed/FPS?

hey Rudski, welcome to the forums!

i will first recommend you to go get Rivatuner (http://www.guru3d.com/rivatuner/) - if you didnt yet, and look at the context help for more accurate description on the settings.

there is a problem with the implementation of the DXT1 texture compression on the nvidia GPUs. the problem is that the DXT1 decompressor uses 16-bit interpolation which will cause the 32-bit compressed textures to be rendered as 16-bit. the setting will force the driver to create DXT3 compressed textures instead, which improves the quality of the img rendered, but reduces performance a bit. i recommend you to leave it on.
this problem applies not only to the ogl applications but also to the d3d, but that setting will only control opengl. you need Rivatuner to disable DXT1-DXT5 texture compressions under D3D.

page flipping is faster, but some games may not work well with the driver forcing one specific buffer mode so i recommend you to set it to the automatic option. the driver then will choose the best mode to each application.

and as for frames rendered ahead, default values worked always better to me. when anything changed performance was for worse. so you can just leave it at default or trying with the different values and run some benchmarks, so you are sure.
