April 28, 20215 yr Hi all, I've now encountered this problem twice -- first by happenstance, and second when I tried to replicate conditions, and it happened exactly again the same way. I have the following system: i7 8700K 3.7GHz GTX 1080 Ti 11GB GDDR5 X32GB DDR4-3200 RAM Running on an LG 32" monitor at 1440p Not exactly cutting edge, but no slouch either. I've been able to run MSFS decently well on a mix of high and ultra settings at 1440p. I recently did an IFR flight from KDCA to KBOS on the A320, and my performance plummeted on approach, when descending between FL180 and 4000. Ordinarily (from pushback at KDCA through and including cruise), I get FPS of mid-20s in the cockpit and north of the 40s on external. But once I'm on the approach, my computer is struggling to get above 10 FPS, no matter the view -- and it degrades to the point that it's unplayable. I haven't been able to start the approach, let alone land, and ultimately have to quit MSFS by ctrl-alt-del'ing out of the game. I checked task manager on the second, most recent run, and the loads on both my CPU and GPU seemed normal -- about 25% utilization on my CPU. Anyone have any idea what's going on here? Is the sim just broken, or is it something else? I've been thinking about upgrading (see here), and this is really annoying me and pushing me to do so... but if I'll see the same results on a top rig, then maybe I'll just have to shelve this for a while. Thanks in advance for any insight as to what might be going on!
April 28, 20215 yr One thing to try as a test is turn off all your aircraft lights and set "Bloom" off. One of the things that hammers FPS near runways is lighting effects, especially bloom.
April 28, 20215 yr Author Thanks, I will give that a try. But I've had it on before and done a number of flights with runway lights, and this slowdown seems to be a new phenomenon -- it's only happened the last two flights that I have done. Edited April 28, 20215 yr by Jetguy87
April 30, 20215 yr Author This didn't seem to do it. I also tried uninstalling the most recent Windows update (KB5001330) that supposedly causes problems, but that didn't fix it either. Any other ideas? It's really ruining the experience 😞
