NVIDIA GeForce GT 610 On Linux
The GeForce GT 610 even with the proprietary NVIDIA drivers will run sub-10 FPS at a low resolution of 1024 x 768 for both the Unigine Heaven and Valley OpenGL tech demos on Linux. The Radeon HD 6570 is just marginally faster than the GT 520/610 and HD 5450/6450.
The GeForce GT 610 with the NVIDIA binary blob is even too slow to handle the open-source Unvanquished game at 1920 x 1080.
