Try my new benchmark!

This is an OpenGL app I wrote, which draws the Mandelbrot set using pixel shaders and l33t colors. It's only the first part of my benchmark app that I'm working on, but it works well already. Post your rig and what fps you get. Note that it requires a SM3 compliant video card to run.

Update 6/4/06:
New version released.
-resolution is lowered to 1024x768
-added interactive features
-keys are: ESC to quit, Left mouse btn to pan view, mouse wheel to zoom, middle mouse btn to reset view, TAB to toggle info, F2/F3 to decrease/increase iterations per pixel, Enter to run the built in benchmark.
-Benchmark will only run once until the app is restarted.
-no cpu bench yet...
 
It runs a loop, drawing the fractal to a screen aligned quad. I'm working on adding interactive functionality like zooming and scrolling, as well as a cpu test, but for now this is purely a pixel shader test. BTW, keys are ESC to quit and TAB to toggle info.
 
13 frames per second with my rig set at stock, is that good or bad?

Also, I hit escape to stop the test. Does it need to run until its own end or do you just need to run it until the FPS settles down?
 
Is it just supposed to sit at that same screen with the circles?

That's all it's doing for me, & fps is staying locked at 30

Yeah, that's all it does for now.
 
I guess I don't connect what appears to be a 2d still image with pixel shaders and such...

Oh well.

I'm gonna try and go for 6fps!!! YEAH!!!
 
I got 8fps on a 7800gt overclocked to 550/1320 How does this bench compare with real world games will i really get that much more performance with an 1800xt or 1900xt? My fps in BF2 are about what an 1800xt gets. I know I would be more limited with shader intense games but this program seams to only stress shaders.

Uhh, I get 11-12 fps on 7900GTX SLI at 720 1822. Seems a little low, :laugh:

Somehow I don't think my SLI shaders are 25% the power of one X1900XTX :laugh:

By the way Opty 170 at 2400
2 gigs of memory at 2.5-3-2-7 1t at 218
Raptor blah blah
 
9fps. I feel bad compared to the X1800XTs, but then I saw the 7900GTX SKI score. Munky, is there any real-world application of this at all? I know it is only measuring a very specific type of performance, but still - X1900s having 3.5x the performance of 7900 series cards? Is there any possibility any actual game could ever be so shader biased to actuallly have numbers like that?
 
Ok, the shader's in the app use dynaminc branching and looping, that may be the reason why the x1k cards are getting better scores. But I didnt expect them to perform that much better. The only other method I know that can accomplish the same result is to replace the loop with a multi-pass algorithm, which will run on SM2 hardware and gets rid of dynamic branching, but I found it actually runs slower on my card than the single-pass method. I may include that option anyway just to compare performance on different cards. And if you thought 4.5fps was brutal, wait till I finish the cpu test! 😛

Anyway I'll post an updated version, which has some changes and interactive functionality.
