In the 'System 3' configuration, Unity is not usable due to serious rendering issues. Open Source Radeon driver: can exhibit rendering artifacts on some systems.With the fglrx driver, you will be missing features such as Kernel Mode Setting (KMS). Fglrx driver: We have had some issues with the fglrx driver but we have been able to resolve them.This is the same program we run at boot time to decide if Unity will be started or if a fall-back should run instead. It will tell you if your system has the required capabilities for Unity. There is a test program in Natty for that. No, Unity tries to take advantage of features that have beeen specified or released many years ago. Is Unity dramatically raising the minimum graphics hardware requirements? (*) Except for GPUs with no appropriate driver support or missing features. GPUs released by Intel after the GMA 950 (*).GPUs released by NVidia and AMD over the last 5 years.All GPUs released today by either NVidia, AMD or Intel.The following hardware have the required capabilities for Unity: Vertex/Fragment assembly programs: 2002.The release date of some key OpenGL extensions is a good indicator of when they where first made available by graphics hardware vendor such as AMD and NVidia.

They help us determine of far back we can go to find GPUs that can run Unity. Here are the GPU hardware release dates of our test systems. Enough registers for vertex and fragment shaders programs.The system must also have support for a number of OpenGL extensions. Because of the decoupling between OpenGL versions and the first implementation of new extensions by hardware vendors, just having OpenGL 1.4 is not enough. We consider the system stability, as well has its responsiveness and graphics rendering performance. Here are the results of our initial experiences with the systems listed above. System 5: AMD Socket A Athlon XP 3000+, 2G RAM, NVidia Geforce 6200 + free nouveau 3D experimental driver, 1280x1024 screen resolution.System 4: Pentium 4 2.4GHz, 1G RAM, NVidia Geforce 6600 AGP (128MB) + Proprietary NVidia driver, 1280x1024 screen resolution.System 3: Pentium 4 2.4GHz, 1G RAM, ATI 3450 AGP (256MB) + open source radeon driver, 1280x1024 screen resolution.System 2: Pentium 4 2.4GHz, 1G RAM, ATI 3450 AGP (256MB) + fglrx driver, 1280x1024 screen resolution.System 1: Dell Mini 9, 1G RAM, GMA 950, 1024圆00 screen resolution.We make the reasonable assumption that newer hardware from AMD, Intel and NVIDIA will be even more capable than the one listed below. We use the systems to identify the minimum specs required for Unity. We have tested Unity on the following systems. Demystifying Unity's Graphics Hardware Requirements
