ISSUE DESCRIPTION
Since SU5, I have been experiencing massive severe FPS drops when near my arrival airport. These aren’t just ordinary microstutters, it can get as low as 4fps for 5 minutes with no solution other than ending the flight and restarting the simulator.
Prior to SU5, I never experienced such issues close to this severity, the simulator was running pretty smoothly. I have had these issues throughout the beta and stable versions of both SU5 and SU5.1.
Rolling cache, shader cache, BIOS, drivers and community folders were cleared with no effect. I also did a full simulator reinstall.
Similar reports have been posted regarding main thread stutters, however they all seem to make mention of stable FPS. This involves severely low FPS with prolonged FPS drops.
Since when loading in and previously I had none of these issues, this suggests to me something has changed since SU5 software wise, rather than it being a hardware or scenery issue.
FREQUENCY OF ISSUE
These issues tend to occur on every one of my flights. Below I have listed every single occassion I have noticed them. Video footage has been included below too. This is really all the flying I could have done as the sim essentially becomes unplayable.
- Flight from YMML to YMHB, performance was fine until short final into YMHB. FPS dropped below 20 and severe stuttering and lag. FPS dipped below 10 fps at the airport during a turnaround state, it recovered after I took off again from YMHB back to YMML.
- Return flight YMHB to YMML, performance recovered when I left YMHB, but on arrival to YMML, FPS dipped below 10 again and had the same issues.
- KDCA to KATL - FPS was fine until short final into KATL. This was with Orbx KATL but FPS again dipped below 10. When I load into KATL I was getting upward of 50 FPS, so this doesn’t seem to be a scenery issue.
- YMML to YSCB and YSSY - similar issues on short final, more severe when landing into YSSY, reaching 7 fps during and after arrival
- YSCB to YMML - less severe stutters on arrival into YMML but then was experiencing 7 FPS again after taxiing into the terminal.
