Same thing here. Puffy bright cumulus clouds now look dithered, and way dithered at that. Tried resetting the graphics settings back to their default values as well as adjusting individual settings, no luck. Tried real weather as well as all the different cloud options. It happens at different resolutions and graphics This started after the 22nd December update (1.12.13.0). This is on a new computer builld that has nothing else installed other than a stock windows 10 and the simulator. The NVIDIA drivers have not been updated in months. No overclocking of anything. Up until this update the graphics were flawless.
Found this megathread regarding the problem, seems like it’s been around since day 1.
Really odd why a perfectly working pristine system would be suddenly affected by this.
As a team member for the first Macintosh I remember, Steve Jobs used to come into our lab at the weirdest times. If there was something that did not work right in the user interface he would single out the coder and ask them “Really, is this the best you can do?”. I miss that with current times software.
