Oil starvation goofiness

The floating point accuracy issue never affected the physics (for reasonable distances) since those always used 64bit. It was only the visuals that vibrated and yea, that's should be fixed now (I'm surprised I read so little about that, given the amount of complaints we got about that before)

I'm guessing a lot of people don't actually run megamaps that often, or got so used to the shaking that they haven't noticed yet. Like I said, I had to turn all my mods off at first to get anything to load.

But now that I know, I'll have to go see

My vanilla customized Moonhawk that I use as a default has issues with random oil starvation, especially on undulating roads. However, I also discovered by using the engine thermals debug app that sometimes it will oil starve quite significantly, enough to start racking up a tiny amount of damage, just by flooring the throttle from a stop. (It has a 2.64:1 axle ratio and rides the clutch up to about 25MPH; dumping the clutch and spinning through first gear seems to prevent this). The odd part is, it seems to be completely random when this happens, and it seems to be coming from oil starvation XY (which I assume is excessive lateral G-force) rather than oil starvation Z. As I mentioned to start, it will also throw an "engine is starved of oil" message in canyon runs, though this also seems to be unpredictable; on one hand, I did manage to trigger a momentary hiccup by getting light over a crest, but on the other, much more severe lightness and even a couple of jumps didn't faze it previously, and previous oil-starvation incidents may not have matched particularly well with topography.

It's on Radial T/As with a race oil pan, there's no way it should ever have trouble with excess lateral force.

Climbing hills seems to cause problems with the game's oiling system in general. A Bolide 320 GTT, when climbing a hill, can enter a state where even a slight squirm side-to-side will trigger oil starvation, though not enough to actually damage the engine; this is difficult to replicate. More significantly, on a previous occasion when I was messing around with the Shutoko mod map, I found that an all-vanilla Wendover with a maxed-out 4.4L V8 will very repeatably oil starve, enough to cause damage, when traveling uphill at speeds over 220 MPH; backing off to below 220 would prevent this. It only seemed to happen in one specific tunnel on outbound Wangan and not on any other uphill section, so I assume a very specific climb angle triggered it.

But wouldn't a race oil pan fix that? Because that seems to happen to me but whenever I install a race oil pan, it doesn't happen anymore

My default has a race oil pan, still happens, but probably less than with a stock oil pan.
