avoid Nvidia beta drivers 320.00 with 6XX GPUs

[John Rofrano]

[David Alfredo] “Nvidia pushed these new 320.00 beta drivers that improve gaming performance while breaking whatever they fixed for Vegas Pro GPU rendering…”

Thanks for the heads-up David. In general I would stay away from any drivers that are not WHQL unless they solve a particular problem that you are experiencing and can’t wait for them to be qualified by the Windows hardware lab.

[David Alfredo] “seeing as their 7XX cards are coming before the summer we can safely say the 6XX/GK– Kepler cards will have a 0.1% chance of ever being fully supported as Vegas Pro rendering/encoding acceleration GPUs.”

Are you saying that the 700 series will yet again have a new architecture that Sony will need to support? If they are still Kepler then all the more reason for Sony to add better support for both so I would think this is actually good news.

John, the 7XX series are 6XX Kepler cards at heart (based on the same iterations of the GPU core) with improved memory bus and a bit more shaders and CUDA cores… they are pushing computing performance to try and catch AMD by adding full FP32 performance back to the intentionally “crippled” GK104 GPU, the architecture is not much different from Kepler, only refined and without “rough edges” (sorry don’t know how to say it in English) so no more weird 192 Bit memory bus for 770 Ti, a traditional 256 Bit is the minimum with 384 for GTX 780 at the same price if not a bit cheaper than currents 6XX cards…

so those contemplating upgrades might wait a couple of months, for the same price of a 660 Ti you can get a 770 with much more horsepower and non-crippled computing performance for professional use.

also forgot to mention the built-in video encoder/decoder in 6XX hardware, actual silicon devoted to video processing not present in other cards… it’s a shame only a couple of companies are using it since it is mighty quick with minimal GPU resources as it is a separate hardware on the Kepler GPU die, if Sony was to optimize Vegas for this separate encoder while using the CUDA cores for rendering acceleration at the same time… I guess performance would be past ahead of some Quadro cards, that’s why FP32 is crippled and Software Development Kits for this Kepler feature(NVENC) are only handed to a bunch of game companies but no professional who could use it “against” the Quadro cards.

it’s like carrying around a ton of toys and telling kids they can’t play with them, 6XX Kepler mainstream cards have interesting and powerful features for video editors that will remain untapped and forgotten since some Nvidia executive decided they were too good (and too cheap).

Wow, Sounds like waiting might be the prudent thing to do.
