Hm, nemam pojma ima li neki od programa tipa Everest tako nešto.

Mislim da ne - jasno ti je zasto pitam; ne pada mi na pamet skidati par gigabajta nekog 3D Marka koji ce davati 0.1FPS makar zalemio te NVSice direktno na procesor... Steta sto nije 8xxx serija u igri pa da iskoristim CUDA-u...

Evo zgodne stvarcice:

THE SERIOUS MAGIC TEXTURE DOWNLOAD BENCHMARK v1.0
http://www.seriousmagic.com

PURPOSE:
This benchmark was originally developed for internal testing at Serious Magic. We have released it publicly so that those who care about improving 3D graphics performance can see what we've observed. We believe it exposes a significant issue in PC graphics card performance. While today's graphics cards can render images very quickly, the software drivers are painfully slow at getting rendered output back over the AGP bus and into the PC where it could be saved and put to work by users. Current generation software drivers achieve only 1/100th of the theoretical download transfer speed that the hardware you've already paid for is capable of. It's remarkable that a graphics card with a video input and some video recorder software can record TV-quality images to the PC hard disk in real-time, yet the same card can't record it's own renderings at even 1/10th this speed. 

The problem isn't the hardware, it appears to be the software drivers. This is supported by the fact that the external video input to a VIVO-enabled graphics card can be moved over the AGP bus very quickly. The speed of transfering the 3D rendered results of the same card is very, very slow.  Yet it could be dramatically increased simply with revised software drivers. However, it appears that no manufacturer has yet made this aspect of driver peformance a priority. The first card manufacturer to address this performance issue would offer the following significant benefits to all the users of their hardware:

- Their graphics cards would become invaluable for rendering production output for TV, film and video. As things stand now, for typical video resolution images only about 5% of the time is spent on rendering. Why? Because today 95% of the time must be used just to transfer the rendered output back to the PC. This effectively nullifies the considerable advantages gained from the amazing speed of the graphics card hardware.

- Software could be written to allow users to actually record game output in real-time without much impact on game performance. After playing there would be a compressed movie of your game play saved on your HD. On a reasonably fast machine you could actually record your game output digitally via Firewire to your DV camcorder as you play or even compress and burn it to a Video CD or DVD at the same time you are actually playing. 

- Screen capture software that grabs motion images of user interfaces for the purposes of tutorials and training is a vital business application. Yet these useful recording tools are currently limited by the graphics card software driver to transfering only a few full-screen frames a second. It should be simple to record 30 frame per second output to your hard drive but this is unfortunately not possible due to the texture download issue. The first card manufacturer to revise their software drivers to address the issue will have significant appeal among businesses, training and graphics professionals.

- Despite the popularity of Internet streaming, it is not currently possible to stream real-time rendered output from graphics cards over the Internet. The network connections, PC processors and codecs are all fast enough today. Sadly, all of this horsepower is being held back by one remaining weak link; the texture download speed of today's graphics card drivers.

Ova 1x daje ~150MB/s dok ova na 8x daje ~1050MB/s...

Svejedno bih volio provrtiti kakav maleni 3D testic cisto da jos i to potvrdimo.
