Slider to adjust/disable the scenery culling (reduce panning pop-in and stutters)

Sim Update 5 brought some huge CPU performance and RAM consumption benefits by culling the scenery not visible in the player’s current view. However, it means that panning the camera quickly or switching views can cause frame drops or stutters, and some obvious terrain morphing and object/photogrammetry pop-in. To many this is an acceptable compromise for better performance, but for some people this is too much of a trade-off, especially for those with high-end computers that are not interested…

A slider is needed control the LOD pop-ins. It's a very easy solution to implement that will make all happy

Very much agree. I enjoy the performance boost but I have enough headroom where I could crank these up and still get very good performance.

Off Screen Terrain Pre-Caching Causes Extreme Stuttering After Update 7

‘Brief description of the issue:’ After update 7, “Off screen terrain pre-caching” is causing stuttering and performance issues. Setting this option to a lower setting is supposed to provide better performance but it actually makes the performance worse. This is related to other posts about terrible performance when changing to left/right cockpit views, etc. Theory about what’s happening: A lower value is supposed to load less geometry in memory. But previously, when new geometry needed to…
