I’m getting the feeling that a this is a server/data issue rather than something to do with a hardware or system setup as the problem seems to be intermittent: I just did two flights with different aircraft with full online and AI traffic with no problems at all and smooth graphics all the way: latest mod working title CJ4 (which just gets better and better BTW) from Gibraltar to Ibiza and a DA40 flight across North Wales with a lot of online traffic around. Last nights flight from Bournemouth to Gatwick with same CJ4 and nothing different on system or game setup had the judder issue so it could just be a data or server overload/speed issue when there are a lot of people using the system…ho hum
