Poor Performance Issue (May be bug)

[TristonStuart]

Noticing poor performance when running engines with multiple cylinders, but my CPU isn't maxed out and neither are any of the cores. FPS will do a weird spiking and dropping thing, the engine will turn over but not run by itself, and the game will run slow and not smooth.

Could simply be a processor speed issue, but I thought it was weird that my CPU cores weren't even being maxed. Noticed that they wouldn't go much past 50%.

I know some others were experiencing this and I wanted to add it as an issue in case this is a bug and not just hardware limitations.

I have an i7-7700 processor for reference (4 core, 8 thread, 4.2ghz boosted).

Same here with an i5 8350 won't cross 70% per thread and similar usage on the gpu, but this only occurs when I load anything above 2 cylinders

This might be fixed in the next release. I think the fluid simulation settings were set too high.

that mainly happens because intel cpus are best in single threading and i see no issue on my amd cpu

and it is a weird glitch and is fixed on 1.4a version, on that version there should be no lag whatsoever

I'm using the 1.4a version release on my i5 9300h and the performance issue is worse compared to 1.3a version release. The latency really likes to jump around from 100 to 500 and back cyclically
