Grant Williams Posted June 12, 2020 at 01:26 PM Posted June 12, 2020 at 01:26 PM Overview Hey everyone. Happy Friday! I am hoping someone here can help me out. I am running X-Plane 11.5b10 with Vulkan enabled. I was also running xPilot, Discord, VATSPY and have VividSky and xVis (those use the Lua script). Additionally, here are my PC specs: Windows 10 Ryzen RX5700 XT 8GB Ryzen 7 3700X 32GB RAM The problem Yesterday I decided I wanted to do a decently long flight from Honolulu to Tahiti. I loaded up on VATSIM in the stock 747-400 with an Atlas Air livery (this one that is not technically for the stock) and took off. After a little over an hour in the air, I noticed a major drop in FPS that consistently got worse as the flight progressed. I started the flight with 60 FPS (which is pretty much what I always get unless I am at a big airport and it drops a bit) and maintained that for much of the time. However, after a while my FPS dropped to 30. I figured it was because there were a lot of clouds so I changed the weather to be VFR and get rid of the clouds... no change. As the flight continued my FPS dropped a little bit over time. 29... 28... Eventually it got down to 25 before I just quit the flight because I knew something was up. Does anyone have any thoughts as to why the FPS would drop so significantly and continue to drop as the flight goes on? This is frustrating because I have a really great computer and if this problem continues in the future it means I can't functionally do a flight over like an hour and a half... Any and all help is appreciated! I will be away from my computer for much of the day so may not reply until later this evening. Thank you all!

Robert Shearman Jr Posted June 15, 2020 at 03:07 AM Posted June 15, 2020 at 03:07 AM Grant, I don't know if this will help or not. But I occasionally notice my sim bogging down after being online for a bit, and this seems to help although I've yet to convince Justin to investigate it further (or, he hasn't seen my posts, or, he's working on bigger show-stoppers or whatever). If I hit the Disconnect button on xPilot, then close xPilot completely, then restart xPilot, then reconnect to VATSIM, that often helps with the stuttering. Oddly enough, it's often not until that very last step -- reconnecting -- that the issue seems to clear up. Again, it may be my imagination as I've no firm data to support this, but, you can try it and see. If it helps, maybe you'll be more successful than I at collecting the correct datapoints to support this representing some bug in xPilot. Cheers, -R.

The alpha version of xPilot includes a garbage collector to automatically unload CSL model objects that are no longer in use.

If 1.3+ has rectified this issue, that's great news. Thanks! Cheers, -R. Link to comment Share on other sites More sharing options...
