Default Massive stutter on PG map

Good evening.

I've experienced massive stutter and freeze of the sim using NS430 in the Persian Gulf map, using terrain mode, expecially when i use high range map (range up).

I think is connected with terrain representation when i fly lower than surrounding mountain (with yellow and red obstacles).

Problems disappear when i lower map range.

Anyone experienced this?

I was actually just on the way to post this bug.

Basically the heightmap was not meant for anything that can fly faster than the MI-8. I noticed the MiG-21 in particular experiences massive freezing and stutters when the GPS is either in moving map mode or heightmap mode in multiplayer. The problem gets worse the faster you fly as it has to preload in more terrain and I'm guessing that messes with the client sync.

This is not just in PG, either. I was having this happen in Caucauses earlier as I flew further north. If you stay within the radius of its moving map, it's fine. But as you move out to the outer ranges, that's when the problems arise.

Definitely, definitely needs a more efficient terrain loading algorithm now that every plane can use it. It's only usable now in short bursts, but should be turned off ASAP to prevent stutters. Which is a shame because I was thinking of using it as a replacement for navigation modes in a lot of these planes where you can't put in INS waypoints like the FC3 aircraft.

I talked about Persian Gulf because it's the only map i tried today.

So this problem is common with all maps.

I posted this bug on the wrong thread but it happened to me too. As soon as you are setting up the terrain mode, fps drops to something between 1 and 4. Haven't seen that in Caucasus. It is very obvious that only the terrain mode is causing the problem since as soon as you are setting up any other page on the NS430, the fps goes back to normal.
Tested on an Mi8 on PG map near Khasab (lots of mountains around).

The stutters come from the need for swapping when DCS uses all your RAM to load the height map. If the height map needs to be reloaded (pretty much all the time except if you are in a perfect, level flight and also if new terrain comes on the NS430 screen) you'll have a stutter every second until it is loaded. The bigger the scale the longer the stutters get. It is particularly bad on servers like Blueflag, where if you are not carefull you might end up with what looks like a frozen game after starting a climb because your height map is loading and your computer can't keep up.

Thanks Rex.
Considering that my SSD is an Samsung 970 Pro Nvme, 32Gb RAM and 11Go VRAM on a 2080Ti, and still drop to 1 to 4 fps, one cannot really consider this is a normal behavior, no? I can't imagine how it looks like with a 5400 rpm HDD if so much swapping is required for this mode.

I myself have a 960 M.2 ssd for swapping but only 16gb of ram and when I start a climb in my Mi-8 on blueflag with the heigh map on a 10nm scale, it just kills my game, last two times it happened to me I had to wait for my helicopter to crash for the frames to come back.

The graphical bugs while using the NS430 are not a priority, no tester has reported or commented on the massive stutters that occur while using the NS430 heigh map particularly but also when using the moving map and nothing is being added in terms of navaids for the NS430.
Is the NS430 being worked on ?
