Hi, JeGX! Stefan is missed because he's offline since september 24th. Why?

3D-Tech News Around The Web / GPUPI - OpenCL GPU (CPU option)
« on: November 12, 2014, 10:17:21 PM »
About two months ago our beloved Turrican passed away in a horrible car accident. He was a big part of our community and is still Austrias only overclocking lengend! Out of my sadness and anger I started to work on this project as a virtual monument, something to honour him in our scene. It's an homage to SuperPI, that Turrican benched on every possible platform, an application that calculates pi completely parallelized on a graphics card. So let's get our gear going and do exactly what our Karl showed us in all his years: Bench the hell out of it!

More info


I got running i5-2500K@4.5GHz and GTX 580@reference-stock 3GB-344.60WHQL:
At 32 millions-digit:
-> GPU

result: 0.681s

-> CPU

result: 17.313s

GPU is 25.4x faster than CPU! :D

GPU - 1 billion-digit: :D

result: 57.095s

General Discussion / Furmark (Win): average bug

I detect "average" bug in Furmark because mathematically the average must be superior than minimum.


General Discussion / only ~50 fps in ShaderToyMark before bench
« on: July 19, 2013, 06:39:11 PM »
Hi! :)

I got ~50 fps (stutter randomly) before bench in STM running XP x86 SP3 and GTX 480 (306.81WHQL) but I got normal performances in NV demos OpenGL (Adrianne, Froggy, Luna...).

Before driver clean:
I got normal performance (extreme framerate without any stutter) bench but I got (too) slow in same NV demos running same OS with 320.49WHQL.

Any help...

NOTE: I got normal performances in STM and NV demos running Win 7 x64 SP1 and 320.49WHQL.

But notice: please should response - here

General Discussion / New NV GF driver: performance improved

New 320.49 driver improves performance for lastest ShaderToyMark!!! - here :D

NOTE: sorry, I tried to send you PM with few times but I can't work to send. :(

3D-Tech News Around The Web / NVIDIA Graphics SDK 11
« on: April 06, 2011, 04:56:45 PM »
We are proud to offer the NVIDIA Graphics SDK 11 in two versions, one supporting Direct3D, the other supporting OpenGL
NVIDIA Graphics SDK 11 - Direct3D Version

This all-new collection of DirectX 11 code samples teaches developers how to make the most of the latest GeForce GPUs. The SDK includes a browser, clear code samples, detailed whitepapers, and videos.

Featured samples include: 3D Vision, hair, FXAA, horizon-based ambient occlusion, stochastic transparency, terrain tessellation, opacity mapping, FFT ocean rendering, and more. - Direct3D 11 SDK download included :) But OpenGL - coming soon...

NOTE: You should change this thread to section "3D-Tech News...".

Great news:

Subpixel Reconstruction Antialiasing (SRAA) (...) In this way SRAA resembles Morphological Antialiasing (MLAA by ATI-AMD)(...)

Fermi (GeForce 400 series or better) may work this new method of AA but I don't know if nvidia confirm... :)

3D-Tech News Around The Web / RTGU 3d technical demonstration released
« on: January 15, 2011, 08:09:28 PM »
A technical demonstration showing an interactive virtual model of an hotel lobby, is available for download. RTGU is a realtime 3d rendering pipeline - composed of a set of tools, ranging from 3d content export/conversion to realtime 3d rendering using OpenGL. The model is completely designed using 3dsMax and V-Ray, then exported and lit using RTGU tools, and rendered using OpenGL 3.x features : rendering uses FBO to do HDR rendering in RGBA16F textures ; tone mapping relies on ARB_texture_multisample extension to resolve MSAA ; linear rendering is achieived by using sRGB textures and framebuffers ; lighting is stored in HDR textures (2D/3D) as lightmaps and spherical harmonics.
Enter site RTGU 3d and click download. :)

But I don't like this demo because the solar shadows are fixed. And its aren't realistics due to without PCSS (Percentage-Closer Soft Shadows).

The author has a topic at Ozone3D (in french).
