webplus Posted February 14, 2015 Share Posted February 14, 2015 I've just replaced an old GeForce GT9400 with an Asus GeForce GT610 Silent (2GB), and although everything else seems to work well (OOB), I'm having problems saving images in both Preview and Pixelmator. If I edit and then save in Preview, the saved image has lost most of its colour (i.e. blacks and dark greys become very pale, blue becomes violet, some images become almost totally white). In Pixelmator if I try and colour-fill an area, the image becomes corrupt, similar to the effects in Preview. None of these problems happen using GIMP. Also doesn't happen booting into safe mode with -x. I switched the new 610 card into another hackintosh and the same thing happens (it's set up the same way as my main). If I use the original GT9400, Intel HD3000 or ATI 5570 there's no problem. I'm not using any extra kexts, tried with GraphicsEnabler=No (and Yes), IGPEnabler=No. Any idea what is wrong and can it be fixed? I'm using Yosemite 10.10.2, the latest Chameleon, a Dell 21.5-inch (1920 x 1080) display. I could exchange for a different nVidia card, but I've read this sort of problem exists with other nVidia cards. Thanks... 2 Link to comment Share on other sites More sharing options...
Zenith432 Posted February 15, 2015 Share Posted February 15, 2015 I got GT 610 too. Can reproduce said problem. When I modify an image and save out of Preview - resulting image is nearly blank (all white.) If save w/o editing the image - no change. Maybe some problem with CI. Other than that I'm very happy with it. QE works out-of-the-box. I've used Intel built-in graphics with no QE for many years - and never seen QE So I'm very very happy. The nvidia card also boots better without screen blanking - and the display image is smoother and seems less flickery. Windows built-it benchmarking reports that performance is a little less than Intel built-in, but I don't care. 1 Link to comment Share on other sites More sharing options...
horizoli Posted March 21, 2015 Share Posted March 21, 2015 Some small error can be! But it is very annoying! LiveQuartz.app works well! http://www.rhapsoft.com Link to comment Share on other sites More sharing options...
Riley Freeman Posted March 21, 2015 Share Posted March 21, 2015 I could exchange for a different nVidia card, but I've read this sort of problem exists with other nVidia cards. Neither of my nVidia cards (see sig) have this issue. The 210 is Tesla, while the 670 is Kepler. The 610 is Fermi and having owned a 460 I can confirm that was the proverbial "bag of hurt".

mitch_de Posted March 29, 2015 Share Posted March 29, 2015 Yep, also happens with my GT 440 (Fermi) no other probs, OpenCL works good. I think Apple has an bug in IOIMAGE Framework which handles Image open, save. Its not an grafikdriver prob , Apple + Nvidia drivers doenst matter in this Preview bug case. I use an older Preview Version (10.0) Finder INfo 7.0 and the prob leaved. Which newer low power (lower cost) GPUs works well with Preview (version 8.0) ? Whats about that Maxwell GTX 730-750 gpus. Or low end Kelper (i dont know names). Link to comment Share on other sites More sharing options...
