Does this increase seem reasonable with Detonator FX?!

Application detection...Shadermark is now a target.

Interesting. Someone need to get to the bottom of this
I've done before/after screenies and also compared it to R3x0, Shadermark looks identical in all cases so there's at least no visual degredation
I also ran Humus mandel brot demo on my 5800 just now and it has nowhere near as crappy IQ as hardware.fr's shots
downloading the rthdribl demo now
in humus mandel brot demo I get 53 fps constantly btw

1024 x 768...10-12 fps is not what Nvnews users were getting, they were getting 5 fps.
Set the resolution in the options menu..F2

You have to zoom in on the Mandelbrot Demo to see the precision differences, can you post a screen shot ??
I don't really understand the results. IMHO either the FX5600 should be slow but with good image quality at PS 2.0 (if it's executing the shaders properly with FP32 precision) or it should be fast with crappy image quality (if it's forcing everything to FX12). Could also be something in-between (if it's forcing things to FP16). However, it is not only really slow, but the image quality is crappy too. It almost looks like nvidia got all cheats backwards, so they render everything always at fp32 but when you take a screenshot they will use FX12Ante P said:Doomtrooper said:
F'ed up. So are they forcing FX12 for everything now or what?
(just a silly joke).Looks like the drivers could need some work? And no, that's not a suggestion that there aren't enough cheats in them

Click on the scene with the mouse and it will freeze the rendering, then press home which will take you back to the starting scene...to resume rendering press pause.
The issue with dynamic range demo is probably the DX driver. As discussed before, the FX can only use 8 bit per component textures storage (apparently still true in the recent drivers?). If conducting multiple passes using 8 bit integer textures, it would save a bit on bandwidth, but if the bottleneck is computational, it would still be slow even though the image quality suffers.
