And now there is talk of OpenGL 4.x. High-Tech MacBook Pro at the best.I am trying to implement stimuli using 10 bits per colour.Apple Pro Spec For Ati Radeon Hd 5770 1024 Mb Update For Mac Apple Pro Spec For Ati Radeon Hd 5770 1024 Mb Mac Store But Apple Pro Spec For Ati Radeon Hd 5770 1024 Mb Mac Store But. 2 GHz Quad-Core Intel Xeon Memory: 16 GB 1066 MHz DDR3 Graphics: ATI Radeon HD 5770 1024 MB. Being a dual-slot card, the ATI Radeon HD 5770 draws power from 1x 6-pin power connector, with power draw rated at 108 W maximum.2 (2012/Nehalem) Specs. The GPU is operating at a frequency of 850 MHz, memory is running at 1200 MHz (4.8 Gbps effective). ATI has paired 1,024 MB GDDR5 memory with the Radeon HD 5770, which are connected using a 128-bit memory interface.835 user benchmarks for money against the moment. This is how to flash an ATI Radeon HD 5770 graphics card for use on a Mac Pro. A less expensive, memory with six mini DisplayPort outputs.

Stats software for macI'm currently working on 10 bit support over HDMI with AMD gpu's like yours (all HD-5000 and later models) with the open-source driver. OSX at least as of 10.9 is incapable of native 10 bit support and our tricks only work for true 10 bit over VGA, with no way to ever support this over digital outputs.The situation is different on Linux, where you can get true 10 bit over analog VGA with our Native10Bit support on AMD graphics cards, and with current NVidia graphics cards, and also true 10 bit over DisplayPort on NVidia gpu's and probably AMD gpu's with at least the open-source driver. If you connect any digital display device like DVI, HDMI or DisplayPort you will only get 10 bit dithered output, ie., 8 bits which are made to look like 10 bits via spatial dithering. We know the HD 5770 works under Linux with 10 bit and the code path is mostly the same, so if you have the same kernel driver and mex files as Ian then it should work on your card.However: This 10 bit framebuffer support only outputs true 10 bit resolution over analog VGA (VGA connector or DVI connector or maybe HDMI connector via proper adapters, in all likelihood not active (Mini-)Displayport -> VGA adapters). PTB beta is currently less up to date than 3.0.11 final, as i try to defer the start of the 3.0.12 series atm.You'd probably need the new kernel driver and the new Screen, then it should probably work. Both have been fixed in i think my repo and in the official Psychtoolbox-3.0.11 final branch ( not the PTB beta).
