GTX670 for the win

Recommended Posts

I have seen xplaneuser's videos (our aussie linux friend) made using his GTX680 and started drooling since last week. =)



Hence  - I have picked one up for the 'pro; un-boxing and hookup will be friday night; and will attempt to make mincemeat out of our XP10 photo-scenery.


FWIW, GTX670s are now selling under $399 in Australia. To any Sydneysiders on the list - head to Ti Computers in Crows Nest.

Ooh you're going to love that card Chris! Expect an easy 30% improvement in fps, though I'm only guessing, you might already have a 660 in there. Doubt it though!

Thanks mateus, Simon, Cameron for the words of encouragement. =)

As to Simon' query: I am currently using a Toaster (AMD 5770), which is an upgrade from my previous Videocard, which was a Potato. (AMD 4870)

Note those cards bench-out at approximately the same rendering power, with the Toaster having 1gb VRAM vs the Potato with only 512, which was my only reason for swapping the card with another Pro I have access to. Neither card performs any better than something from 2009 or so.......

Which is why I'm rather excited to take this leap of at least 2 generations of card technology & performance.

Water Reflections -> Complete... For the Win.


As suspected Simmo - Im now CPU bound. Had to cut down the objects/trees.


I also opened a bug with Ben! I found out that if X-Plane detects any nVidia card under MacOSX - it disables hardware instancing!.. since the 320M/330M is software emulated; Ben threw 'em all into the same category (unsupported/emulated, so XP disables the call) Unfortunately, he needs to *actually* check if the card is a Fermi or Kepler based card. (and turn it on) heh.


... Which explains the poor "number of objects" performance, regardless of HDR, Shadows, Water, etc...


Mac OS X 10.8.2 CPU type: 1801080018 (unknown PowerPC) CPU speed (mhz): 2925 Bus speed (mhz): 4800 RAM (MB): 12288

Disabling instancing for DX10 NV hw - it is software emulated.

OpenGL Vendor    : NVIDIA Corporation
OpenGL Render    : NVIDIA GeForce GTX 670 OpenGL Engine
OpenGL Version   : 2.1 NVIDIA-8.1.0 (210/0)................GLSL Version     :1.20/120
first-gen shaders: 0 (16/4096/124/16/16/4096/4096)
This video card is: DX10 - No instancing (found glMapBufferRange)


Ok enuff playing. It works.

Hah! This is the direct result of a series of tests and email exchanges between Ben and myself over the past few days.


Turns out (so far)


1. Apple Native Drivers are *faster* than Nvidias updated OSX 10.8.2 drivers (posted above) (go figure)


2. No Instancing is *faster* than Hardware Instancing. (go figure)


He needs me to test the exact same setup but in Win7x64 - which I'm about to bootcamp the 'pro to make work. (need to dissolve my HW RAID-5 first..)


We'll keep you posted!

Yep - Applies drivers are better than nVidias Drivers under OSX


Yep - AMD cards are just generally much better than an Nvidia Card under OSX
