Optix 2.5 released - up to 1.5x faster performance

[ricardonuno1980]

NVIDIA OptiX 2.5 RC1 Now Available!

The Release Candidate for OptiX 2.5 is now available for testing. This important new version provides enhancements that dramatically increase the possibilities for GPU ray tracing, including:

• Out-of-Core Memory Paging
Scene sizes can now exceed GPU memory on professional GPUs (Quadro or Tesla) to the extent there is host RAM available.

• Unlimited Textures
Any number of textures can now be used in scenes (when the textures are not being used in graphics interop).

• Ultra-Fast Acceleration Structure Building
A new GPU-based BVH Builder - HLBVH2 - builds acceleration structures fast enough for interactive editing and deformation.

• Increased Performance on Divergent Rays
Techniques such as path tracing and ambient occlusion should see a noticeable performance increase on complex scenes.

• Visual Studio 2010 support

I got in sample "Whitted" running AMD X6 1055T/GTX 480 with Win 7 x64 SP1:
Optix 2.1.1 x64 - 81 fps but 91 fps maybe due to in better Optix 2.1 or better geforce driver
New lastest Optix x64 - 128 fps running 275.33WHQL-HQ!! woowww! But I increase only a bit 132fps running GPU@760/1520/1900 due to my CPU bottlenecked.

I got also improve much rest of various samples!

Mind making a video of the samples?

I got in sample "Whitted" running Win 7 x64 with 295.51beta:

128 fps - GTX 480@stock (86% GPU usage) running AMD X6 1055T@stock
132 fps - card@760core-1900mem (86%) running same CPU speed
135 fps - card@stock (88%) running CPU OC to 3.19GHz
139 fps - card@760core-1900mem (87%) running CPU OC to 3.19GHz

GPU usage improved in videocard at stock after CPU OC enabled. wtf?


NOTE: No comment yet... But... do get any dificulity to gain access download from nVidia?
