![]() TessMark bug with Radeon based cards under Linux ![]() GpuTest 0.4.0 also fixes a small bug with Radeon cards under Linux in TessMark test: Keep in mind that OpenGL 4 is not official and is partially supported on Mac OS X, that’s why TessMark might not run on some Mac systems. That’s why we can run GiMark ( OpenGL 3.3 test) and now TessMark ( OpenGL 4.0) under OS X. But Apple has added some features of OpenGL 3.3 and OpenGL 4.0 in OS X. OS X 10.7 and 10.8 officially support OpenGL 3.2 only (more details HERE). The current state of OpenGL 4 tessellation on Mac OS X 10.8 can be found here: I didn’t test TessMark with a Radeon card and then, if you have such a card (HD 5000/6000/7000), let me know how it works (by posting in the comments section of this article or in GpuTest forum). ![]() TessMark: OpenGL 4 tessellation under Mac OSX with the Intel HD Graphics 4000: incorrect rendering TessMark: OpenGL 4 tessellation under Mac OSX with the NVIDIA GeForce GT 650M: correct rendering TessMark works fine with the GeForce GT 650M while the rendering is a bit perturbed with the HD Graphics 4000 as you can see on the following pictures: ![]() Apple has added in OS X more OpenGL 4 support than I thought, which is pretty cool. I must say that I was rather suprised when I saw TessMark running smoothly on my Macbook Pro Retina (Intel HD Graphics 4000 and NVIDIA GeForce GT 650M) with OSX 10.8.3, after having removed all checks I usually do in the initialization of an OpenGL demo. The version 0.4.0 of GpuTest is available and this time, OS X users can taste OpenGL 4 tessellation on their Mac systems. ![]() GpuTest comes with several OpenGL tests including FurMark (OpenGL 3.2), TessMark (OpenGL 4.0) as well as new ones like GiMark (geometry instancing) or PixMark (heavy pixel shaders). GpuTest is a 64-bit cross-platform OpenGL benchmarking utility for Windows, Mac OS X and Linux. TessMark: OpenGL 4 tessellation under Mac OSX ![]()
