No plans yet, the first is to get a reliable performant water solution.
It wouldn't hurt to backport a few optimization changes. I still can't play the game without freezes (I reported them correctly and they were confirmed fixed, but they are still not in 19.2 due to the team moving on to a20).
Also, there's a problem with the steam store 7dtd's minimum specs (just the CPU).
You should state that we NEED a 4 core CPU minimum system. Multithreaded or not, this game can't run in a 2 core 2 threaded 2.4ghz cpu in any resolution or configuration at a stable framerate.
Hell, currently it can't even run without constant freezes at 4 cores 4 threads 2.7ghz . It MIGHT run at 4 cores after some spawning/ issues are resolved though . 2 cores is unrealistic, naive and even damaging for 7dtd in terms of marketing, mouth to mouth sales and reviews. Yeah, it wasn't unrealistic in alpha 12.5. It's time for a tweak.
Regarding the storage (HDD vs SSD) it should be fine not to put it on the minimum/rec specs IF the team keeps in mind that everything should be loaded on to memory (RAM, and/or dedicated) until the player opens some interfaces (inventory, trader, etc) and even then, the file writing should be delayed, precached and minimal (except on the ESCAPE/PAUSE menu of course).
Bottom line: Please backport optimization fixes ASAP so we can help in detecting the remaining optimization problems. By all means continue with a20 until June, but those fixes are not online yet and they need to be.
