Using a 9070xt with 16GB DDR6 I get error messages that I have run out of VRAM using both TAA and FSR 3. Flight was over Malta using the Diamond DA40NG. I did not get these errors prior to Sim Update 2.
I also have another PC with a 4070ti super also with 16GB VRAM and I have not gotten those error messages. Please let me know if you need any additional details to help troubleshoot this.

In the game I get an alert that I have exceeded available GPU memory and I should lower the game settings. What’s interesting is that I show only 13GB of available GPU memory whereas on the 4070ti Super shows 14GB available. They are both 16gb cards. The 9070xt is a new card and I’ve only had it for a few weeks, but I’ve used it daily and I’ve not had this error until Sim Update 2. Interestingly, I get about 35 FPS in the 4070ti with 4k TAA ultra settings and in the attached screenshot I’m getting 50FPS with the same settings but exceeding my available VRAM. Perhaps it has something to do with how the sim handles AMD GPU’s.
After troubleshooting the issue I think I figured out a way to boost my in game GPU available threshold. I set integrated graphics on my 9800x3d to hybrid mode in the bios. I also set it to game mode and lastly I disabled Resize Bar Support. Your mileage may vary but I am now able to get up to 120FPS using FSR 3 aliasing and frame generation. and around 50 FPS solid using TAA without frame generation. TAA with Frame Gen gets me around 90 FPS which is similar to my 4090 CPU with the 9800x3d on Ultra using DLSS 4 DLAA.
