Irrlicht Engine

Update 23-Sep-2012: Added support for DirectX 10 hardware running through DirectX11.

Another ray tracing demo, though this more of a way of testing my modifications to the DX11 version of Irrlicht that I'm working on than anything completely new. Runs much smoother than my previous Irrlicht raytracing demos though, and has native support for DDS, cubemaps, compiled shaders and more. Anti-aliasing is via FXAA. Thought I would release this so people could see how it runs (if at all!) on their DX11 hardware. More ray tracing demos - of things other than spheres - may follow.

I'm really impressed! Got over 300+ FPS on my system! (NVidia GT460)
EDIT: Sorry, it's a GTX460! My "peak" frame rate is around 380FPS!

Thanks Christian. Performance numbers are interesting. I had a look on nvidia's site just to see the spec's of the card but I couldn't seem to find "GT460" - did you mean GTX460?

BTW If anyone else has any performance numbers I'd be glad to hear them (state the video card as well please).

I've tried to run it on my machine, but I am getting window with message "ERROR: Missing driver/hardware support".

I am using latest nVidia drivers for my card (306.23). Windows is 32 bit and DirectX version is 11.
If you need more information, let me know.

Later today/tomorrow I will try to test it on a rendering computer.

9800 is a DX10 device.

Oh, true! I even didn't know that.

If you want to redownload the zip and give it another try I've just added support for DX10 hardware running through DX11.

I have downloaded a new version, it looks really nice. I got about 135-140 FPS.

As I promised, I checked the app on our rendering machine at work:

By the way, I don't know why it detected processor clock as 3.2GHz, this machine has installed Intel i7-3960X at 3.3GHz.

Perhaps a rounding error... Sometimes the clock could report as 3.299Ghz

Thanks, interesting info. Very good numbers (relatively) on a 660!

BTW The frequency is just being rounded down to the nearest tenth when it's displayed. It's held internally in a 64bit int to the nearest Hz.

Tried it out on my machines (dektop and notebook)

AMD Radeon HD 7900 Series (7970)
CPU: 8 Processors at 3.5 Ghz
running at 1120 Fps

AMD E-450 APU including a
AMD Radeon HD 6320
running at 11 Fps

PS : had to add D3DCompiler_43.dll and d3dx11_43.dll for me to work

really nice work

Interesting numbers, especially the APU. Thanks.

Regarding the dlls - I'd guess that you may be missing the required Microsoft DirectX install (mentioned in the Requirements section of the readme).

Amazing work 1100FPS here. Tell me why arent you part of the core team to add the driver and demos in?
