No they don’t. I’m realy happy now with the performance. It never felt this good! I can’t notice those small spikes if i don’t look at the measured mainthread. Before i had much more spikes all the time and that i could notice for sure. The thing is that it will always feel different when using 30fps constant vs 60fps constant. That we need to know.
Now i have constant 30fps in FBW A320 with Terrain lod at 150 and constant 60FPS in GA with terrain LOD at 150. 60FPS is tricky, there we need to have the mainthread at green all the time. If it gets down to yellow it starts to go below 60fps. I have a hard time to keep it at 60fps because of my GPU and i do not want to set my res lower than 1980x1080 and i can live with some drops in 60 FPS. Drops in 30FPS is more noticable. I think Green stands for 60FPS and yellow stand for 30 FPS RED means below 30FPS. RED is bad bad bad.
One thing you can do if you have a hard time making it run in 30fps smooth on ground is to set the terrain LOD realy low on ground and when you are alittle higher turn up the terrain LOD again.
