r!ppz Posted December 5, 2016 Share Posted December 5, 2016 Since I installed Sierra I have the following problem: When I had the screen locked (I do not hibernate) for a while the whole OS freezes for a few seconds. I can move the mouse and click things but I do not get any visual feedback. Then after a while I get the feedback all at once. So things are happening but the drawing stalls. When I look into dmesg I see that the graphic card has some problems: virtual IOReturn IOGraphicsAccelerator2::newUserClient(task_t, void *, UInt32, IOUserClient **): Too many contexts (0) or command queues (308) created, possibly leaking? virtual IOReturn IOGraphicsAccelerator2::newUserClient(task_t, void *, UInt32, IOUserClient **): contexts(0) and queues (861) exceeding limit (512), failing context creation stalling for detach from nvAccelerator This is just an excerpt. There are thousands of these messages in the kernel message buffer. I attached whole log (I did changed the size of the buffer so they wont get overwritten). Got a GTX660Ti with stock driver. dmesg.txt.zip Link to comment Share on other sites More sharing options...
