[QUADRO] Linux vs Windows | OpenGL vs DirectX | Unigine Valley benchmarked!

[Troyanac]

Oldschool resolutions incoming, beware!

 

So, i benchmarked my Lenovo T61 running both Windows 7 and Fedora 22, both with latest drivers from NVIDIA, in Unigine Valley. 

Some detailed stuffs:

Intel Core2Duo T7500 2.2GHz

3GB SODIMM DDR2

NVIDIA Quadro NVS 140M {

 

16 Cuda cores
DirectX 11

400MHz core clock

800MHz Shader clock

1200MHz memory clock, GDDR3, 128MB of it

 

}

 

Windows 7, driver 341.33 Performance driver

Linux 4.2.3, standard 344.31 driver

All settings set to lowest possible, no AA, VGA resolution.

 

All was done on proprietary NVIDIA drivers, because Noveau is desperate.

 

Linux 4.2.3 OpenGL:

 

Windows 7 OpenGL:

 

 

Windows 7 DirectX 11:

 

 

Windows 7 DirectX 9:

 

 

 

All testing was done in 1 pass, as my eyes were bleeding from the framerate.

Conclusion:
 

As expected, there is that always-present performance gap of around 20% between Linux and Windows, and between OpenGL and DirectX respectively. 
 

 

Also, games i played {

DiRT 3 - Windows 7 - DirectX9 - ~30fps 1024x768 - Lowest / No AA

CSGO - Windows 7 - DirectX9 - 35-40 fps 640x480 - Lowest / No AA
Dishonored - Windows 7 ' DirectX 10 - 20-25 fps 640x480 - Lowest / No AA
CS 1.6 - Windows 7 - OpenGL - ~80fps+ 800x600 - Lowest / No AA
CS 1.6 - Windows 7 - D3D - 100fps+ 800x600 - Lowest / No AA
CS 1.6 - Linux 4.2.3, Wine 1.7.55 - OpenGL - ~80fps 800x600 - Lowest / No AA
AC4: Black Flag - Windows 7 - DirectX10 - ~10fps - 640x480 - Lowest / No AA
Left4Dead 2 - Windows 7 - DirectX9 - ~40fps - 1680x1050 - Lowest / No AA < Suprises me a lot, looks like Source loves Quadros
Insurgency [bETA] - Linux 4.2.3 - OpenGL - Slideshow - 640x480 - Lowest / No AA

I don't know about windows and linux for frame rates but DirectX and OpenGL frame rate differences are really entirely dependent on implementation of the rendering engine. You can't really conclusively determine which API is better purely through FPS numbers. Because there are many little things with the usage of each API that can kill performance, or even it could be a shitty implementation by the graphics card manufacturer (for OGL).

 

OpenGL is giant piece of shit in my opinion from working with it but FPS really isn't a fair determining factor since there are so many variables dependent purely on implementations.

ALL DEM CUDA CORES!!

I know, OpenGL is pretty bad, but im just showcasing end-user framerates
