Fur Rendering Benchmark

Comment

I officially released the fur rendering benchmark 4 days ago. So let’s analyze a little bit the first feedbacks available on forums over the web.

Homepage: www.ozone3d.net/benchmarks/fur/

1 – Fur rendering benchmark isn’t cpu dependent and this is a very good thing for a graphics card benchmark. No matter the cpu speed, the result for a given card stays equivalent:
– oZone3D.Net forums
– extremeoverclocking.com forums
– extremeoverclocking.com forums
“yes the first propper gpu bench ive come across, i really like this…. it stops all the arguments about memory timings and cpu speeds. its a good equaliser as all our systems can provide that 10% cpu info the gpu needs…”

2 – 8800GTX vs 2900XT
ATI 2900XT seems to beat NVIDIA 8800GTX. In all forums, the 2900XT is ahead:
– oZone3D.Net forums
– overclockers.co.uk forums
– extremeoverclocking.com forums

3 – this benchmark seems to nicely overload the graphics card and then is a cool GPU burner and stress/stability test utility.
– clubic.com forums : “Par contre j ai jamais vu ma carte graphique chauffer autant: environ 100° pendant la test:ouch:”
– oZone3D.Net forums: “This thing just succeeded to shut down twice the PSU, caused by overloading of the graphics board!!”

I done a little test with my 8800GTX:
– gpu core temp at rest: 58°C
– gpu core temp at load: 83°C

Okay, that’s all for that small benchmark. :winkhappy:

Quick Review – GPU Caps Viewer

Comment

GPU Caps Viewer is the new I worked on these last days. It’s the successor of HardwareInfos. GPU Caps Viewer is based on the branch v3.x of the oZone3D engine (while HardwareInfos is an oZone3D v.2.x branch based tool). In addition to classic GPU/CPU information / capabilities, GPU Caps Viewer offers two cool features:

– an OpenGL Extensions database. Either you can see the extensions supported by the current graphics card or you can see all existing extensions no matter the graphics board you have. You can quickly select an extension and jump directly to ist webpage (SGI or NVIDIA extensions specs). I must confess it’s very useful for me.

– a GPU-Burner… that was the hard-coding part of GPU Caps Viewer. The GPU-Burner allows to open several 3D windows. Actually you can open as many 3D views you want (1, 2, 4, 6, 10, 20, …). Each view renders a GLSL toon-shaded object with vsync disabled. You can set the size of each window individually (default size is 400×400). Each 3D view is rendered in its own thread… I let you imagine how hard is to debug a multitreaded gfx application :raspberry: And because I’m only a human, there are always some bugs in my code. But there is a very cool tool that helped me to manage the mad threads: ProcessExplorer :thumbup: You can download it here: www.majorgeeks.com/Process_Explorer_d4566.html.

Here an screenshot of my desktop with 13 instances of the 3D view runing at the same time. I will release GPU Caps Viewer very very soon. So stay tuned! :winkhappy:
