Apart for the absurd comments about not offering support, not even taking into account we had the forum down, because we were updating to a new server AND we were hit by the global internet shortage which has affected Microsoft itself and millions of websites running on Cloudflare, the "problem", which of course is NOT a GSX problem, as usual, is clearly AutoFPS, since passengers are carefully optimized with multiple LOD levels, tuned to the default "High" value of 100 ( Ultra would be 200 ).
As a general suggestion: when something disappears because of AutoFPS, it's an indication it has been WELL optimized.
It we just didn't care about fps or memory, we wouldn't have modeled any LODs, so the objects wouldn't be affected by the Object LOD slider. This would have saved a considerable amount of time/money to provide with this free update, and we could have always use the old excuse "our product is so detailed that requires a new PC", which is a lame excuse because nobody will tell you that adding LODs takes time, and nobody like to do that.
