    The MSFS wxr radar is known to act up even on really well spec'd pc's. You could try using this tool, not sure if it will help, but it has definitely cleaned up performance and bugs for me.

    Black Square has custom built wx radar. I don't think it does correlate with the MSFS wx radar.

      @Zacke To my knowledge it will utilize the same data (corrupt or not) on the display as any other weather radar in msfs as there is only one source for the quite crummy simulation of a wxr radar (I think it's just a crop of the NEXRAD image with a different resolution). I have experienced anomalies on pretty much every aircraft that has one, but not since I started clearing cache files regularly.

        That sounds not good.

        I don't know much about that internal MSFS weather processing but didn't it use meteoblue.com weather data which is very advanced? NEXRAD is only available in the U.S. and is quite limited in resolution?

          @Zacke I just meant its the same source as the msfs simulated "NEXRAD" not actual NEXRAD**. As of right now there is no way to properly simulate wxr radar in msfs. You may have confused the Starships custom ground radar which would work similarly in logic to the wxr radar if it could be done.

            Still sitting on the ramp at EGPK heading 190° getting these results with the radar.

            The chart is for your orientation.

            Are these echos on the VP from the landscape?
            Why are there no echos on the normal top down view without changing range or tilt?
            Is the VP a complete different radar mode (not just another representation of the data)?
            And does changing the tracking change anything in the VP mode?

              Just looked at a rw weather radar, there should be a lot of radar echos. But that's maybe a common MSFS problem. 😞

                Now it looks like this and quite realistic.

                By the way: When I fumble around with the gain knob and than moving it back to full the echos are shown very weak though. (photo 3 & 4).2026-03-24-14-31-10.PNG 2026-03-24-14-31-24.PNG

                  I tried this second time while flying in manually entered rainy weather.

                  First sweep gives clean image:

                  After that it's just a mess:

                  Sometimes it starts to mess even middle of sweep, note didn't draw anything on the left:

                    That's what I've mentioned in #4.

                    How do you start your MSFS session/your flight?

                      This is because you have the NEXRAD imagery up on the GNS 530. It's a known bug in MSFS since day one, and we haven't been able to coax a solution out of Asobo yet, to the best of my knowledge.
