Lots of users have gotten smooth perf with default scenery, but others have made it stutter – the rendering settings are flexible enough to do either! 1050, just like 1045, does the best it can, and you will get the performance you get based on your hardware, drivers, rendering settings, and add-ons. So…once we are on Vulkan with out code clean, we can consider a stutter a bug on a clean system. Plugins run synchronously and we know nothing about them. GL makes no promises about perf, so until we move to Vulkan & Metal we’re going to see all sorts of configuration-specific weirdness.ģ. We really can’t guarantee that the underlying driver is stutter-free. But until we fix everything, performance is “best we can.”Ģ. 1050 is better than 1045, in that one or two known causes of stuttering is fixed. We can’t guarantee that all of our code is stutter free. it’s a very short instance of very low framerate (a long frame).ġ. A stutter happens any time the video frame is “late” to show up, e.g. It could be something else entirely, of course, but that’s what I’ve observed and that’s where the clues point to so far. Users with newer hardware will not notice the microstutters, whereas users with older hardware will. The blocks are not noticeable in the SSD case because the thunderbolt SSD is very fast comparable to accessing a spinning hard drive, which is significantly slower. This leads me to believe there may be an issue where X-Plane 10.50 is accessing the file system in such a way as to cause small blocks in the display thread. X-Plane 10.45 does not have a microstuttering issue on either the spinning hard drive or the SSD drive. So in my case, the microstuttering appears when I run X-Plane 10.50 on an operating system using an internal spinning hard drive and does not appear when I run X-Plane 10.50 on an operating system running off a much faster thunderbolt/SSD drive. In the spinning hard drive case, I suppose it’s possible some other part of the OS is causing the micro stuttering, but the reason I lean away from that theory is X-Plane 10.45 does not show the microstuttering with the same plugins. El Capitan was installed over Mavericks). Now admittedly, the internal hard drive installs were both derived from the same older Mavericks install (i.e. My internal spinning hard drive Mavericks and El Capitan installs did have the microstutters.īoth installs had the same X-Plane with the same plugins running on the same exact hardware. My thunderbolt external SSD El Capitan install did not have the microstutters.
