La Calanque is a nice demo and a heavy pixel shader test based on this Shadertoy demo. This test is perfect to benchmark high-end graphics cards.
La Calanque has been ported to GeeXLab, and a ready-to-use and simple benchmark is waiting for you in GeeXLab’s code sample pack (unzip the pack, browse the host_api/GLSL_ShaderToy/ folder and load the la-calanque-1080p-fullscreen.xml file in GeeXLab).
GeeXLab and the code sample pack can be downloaded from THIS PAGE.
Run the demo and read the framerate (FPS). Here are some results in 1920×1080 fullscreen (testbed: Core i5 6600K, ASUS Z170 Pro Gaming, 8GB DDR4 Corsair Vengeance, Win10 64-bit, all hardware with stock clock speeds):
Radeon HD 7970 (Cat 15.1.1) | 5 FPS (avg) |
Radeon R9 290X (Cat 15.1.1) | 10 FPS (avg) |
GeForce GTX 970 (R359.06) | 15 FPS (avg) |
I haven’t tested yet but you should be able to run the demo on Linux and Mac OS X as well.

eg: GTX 970 – 15 fps – min, max or average framerate?
yes I forgot to mention it, I posted average framerates.
Ok. But using “fraps” on Win 10 x64 with GTX 780 Ti Classified at 1080p, I get:
Frames: 1011 – Time: 63656ms – Avg: 15.882 – Min: 14 – Max: 18
I used 358.50WHQL, sorry. 😉
With a MSI GTX 970 OC edition, with OC (gpu/mem -> 1467/1900), and almost 150 secs of testing with fraps:
Frames 2583, time (ms) 146296, min fps 16, max fps 20, average fps 17.656
So, it’s a good improvement from that GTX 970 of your texting, JeGX. Almost an extra +20% with that OC of my card. R359.06 driver and with a Sandy Bridge i5 system (2500K@4.2GHz), and win 8.1.
Ok but we get NO any CPU bottlenecked at default resolution screen (not as 1080p) because GPU usage is 99%.
I have same CPU but OC at 4.5GHz with Cooler Master 212 EVO (air cooler). 😉
Indeed. This test isn’t at all limited by cpu bottleneck.
Check out the forum for new demo pack, especially “Snail” which is yet more demanding.
