I have some huge performance issues with this plane since SU3 which have nothing to with the performance degradation mentioned earlier. For this test I just took off at an empty airport (MKS LSZH) and flew out in a straight line over the alps. Baseline performance on the runway is borderline for my perf target of 80FPS, but still reasonable considering the scenery and city around it. Once I take off it becomes problematic then. It starts stuttering hugely and dropping, but only intermittently. The lowest I have seen was below 20 FPS with FG! And it always show in huge spikes in Main Thread, Manipulators and CoherentGT. I already tried clearing WASM, but to no avail.

There are currently quite a few issues with how the runway 31L touchdown zone is designed. The first ones are on approach, that the landing aids next to the runway are misaligned with the runway itself. As you can see on the screenshot the PAPI is far beyond the ILS G/S antenna here which leads to serious disagreement between the ILS and PAPI while landing. Also neither of these is next to the 1000ft marker on the runway where they should be. This might be due to the runway having a displaced threshold here which should not be case according to the charts and the most recent satellite photos from the airport. Another issue that is only visible on takeoff is that the light fixtures in the displaced threshold of the 31L are acutally hovering in the air as you can see on the screenshot below.
