It looks like the draw calls go nuts under certain circumstances:
- vsync must be on
- FOV needs to be higher than 32
- Look straight up or straight down (does not always require this extreme, but this is the easiest way to reproduce)
When looking at the horizon:
- Cull: 1.5-1.8
- Draw: 1.5-1.9
- GPU: 2.75
- FPS: ~60 (monitor is like 59.98 so it usually bounces between 59/60, about what you'd expect)
When looking straight up:
- Cull: 0.85
- Draw: 7.8-10+
- GPU: 0.5
- FPS: 62.8-62.9
It's noticeable in gameplay, where you'll be looking around for cliff racers or looking down for flora and whatnot, and the FPS will get juddery due to the odd framerate.
- water shader on/off has no effect
- aniso 0x-16x has no effect
- draw distance short/far has no effect
- FOV 32 or lower results in normal behavior
- turning off vsync obviously does the job but introduces tearing, which is why I want vsync on in the first place.
BTW big win in getting 60fps in the inventory. That's something vanilla never accomplished.
