Cars and their Physics

[🆄🅽🅲🅻🅴 🅹🅾]

Many here have lots to say about cars and how they are, yes, the terms I despise most on these forums; "Broken" or "Bugged" . Stories and videos of flying cars, cars killing the player as soon as they climb in, cars rubber banding/lagging/crashing into objects, and so on and so forth.

So we decided to run a test today, and to be consequent and clear about it, here are the hardware:

Server Provider: Fragnet, Community/Public, Vanilla only.
Internet connection: Home Broadband over fiber, 500mbps

PC Specs:
MOBO: Asus Strix Z270F Gaming
CPU: i5 7200, 3.80GHz
GPU: Gigabyte 1070 8GB
RAM: 32GB Corsair Dominator, 2600MHz
SSD
Win 10 Home Pro, 64Bit
Game video settings; 4K High.
V-Sync disabled, 80 to 90FPS

Drove the Ada from Kamenka on the West coast, up to the car spawn at Willow Lake on the N/East coast. All the way there the car was functioning smoothly, but surging/stuttering all the time. At the car spawn we had fixed a Gunter previously, and my friend and I turned around and went the opposite way.

This time with V-Sync enabled.

The ride back was even smoother, with no surging at all, with two cars in close proximity and travelling at speeds reaching 100km/h. No issue, smooth sailing. The V-Sync fix was interesting.

We've had this server almost 7 months now, and we have built, I don't recall exactly, around 3 dozen cars, mostly Ada's, then Olga's and now Gunter's. (Seems Olga's have been removed since they were spawning upside down or on top of things) We crash them all the time doing silly things, but not once did a car kill us by getting into it. Flying car, maybe twice in this time, but not recently. We do find glitching by the door as you try to get in, then the game freezes and you have to log out and back in to make things work again.

I guess what I'm saying is that if you have a half decent gaming PC and a fast, solid internet connection playing on a good server, you're good to go with cars. If I had to score the present state of the cars in Dayz, I'd give them 7.9 out of 10. The points deducted are for the infuriating mechanic cars have, for running backwards on an uphill before they start to move forward, and the insane under powered performance they have on hills, no car in the world is that weak.

Thoughts?

So you deduct points for cars being... well, cars.

My thoughts are your server is always empty. Try using a car on a full 60/60 then come back with your results.

I mostly agree except like Nica said, I dont think you should have deducted points for having low power and rolling backwards on hills. If you look at the date of the vehicles they are replicating, you can see the specifications of them and see that they really were in fact that insanely underpowered in real life as well. I also think it would be a good idea to re-test with a full server and see if the results change. My honest guess is they probably will.



Its very common to roll back in a manual vehicle when being careful while starting to avoid stalling, especially when its engine is weak.

As for the power, the Offroad Hatchbacks performance and partially its looks are based off the first generation Lada Niva.
https://www.ultimatespecs.com/car-specs/Lada/667/Lada-Niva-16.html

As you can see, the vehicle is by no means a speed demon with its 56kW (76 horsepower) 1.6 liter engine. If you look at the configuration file for the Offroad hatchback, you can see that "powerMax" value is 53kW. Thats not too far off the IRL specs. The same goes for the other vehicles. I think you may be comparing the vehicles in game to modern vehicles. Which is understandable. But the vehicles from the game are from the 1960's/1970s and are much weaker than modern vehicles.


In my honest opinion, I would have given roughly the same score, except the point deduction would have been for A. The lack of the ability to lock the differential on the 4x4 to aid traction while offroading(or at least just give it better grip please), and B. the fact that the player character automatically partially engages the clutch when going up steep hills. This would be okay if the engine was at risk of stalling, however this happens even when you're going wide open throttle at 35 kmh in 2nd gear and gaining speed. There is no need to press the clutch in that situation. If you were to do the same thing with a real vehicle, you would end up with all gears behaving as neutrals really quickly. But aside from it being a "this would cause this IF it was real life" sorta thing, it messes with RPM audio queues for gearing. After a while you stop watching the tach and shift by ear. This clutch behaviour screws with that since I hear about 4500 RPM and instinctively gear up, only for the next gear to also be 4500 RPM because the engine wasn't even matching the axle rotation speed in the first place.

7.9 (8 out of 0 is not what I would score 6 at best. 8 would suggest that only basic probs occur. You do know favs. for the game when the devs see this and say, hey see... our game is okay.

Your specs are above average and your controlled test does not hold up to full servers with people of many specs play on. It is not OKAY that a car disapears only every 4 days instead of 2.
Then you have to add, modded vs vanilla. modded servers and cars do way better then Vanilla.

Do not get me wrong. What you attempted seems of value to this game. But your test is very flawed and favors the game and not the full truth of how bad it really is.

This ^^ Try this with 60 players then judge .

I've been experiencing cars destroying themselves on restarts, has anyone else come across this.

yup some cars start moving/flipping/bouncing with a server restart. parked cars aswell as freshly spawned-in ones. if they move too heavy - well the engine gets damaged and the car will despawn and hopefully respawn in a safer position^^

This should be fixed by now, it's been happening since 1.03 and it's pretty significant, especially in servers with base building.

Seems to me OP made a real attempt to start an interesting debate about the game, and you respond with this amazingly empty one liner? Almost all commentators below you also made an effort to share their opinions and experience, so refreshing in these normally toxic forums. Not you though; you chose to be just your usual, holier than thou, acid self.

It has already been proven that overfilled servers with dozens of mods have issues because they are laggy af. Guess why the devs run official servers on 64 players without mods? And it also says in the loading screen that mods can alter your game. So basically everyone complaining about buggy cars but plays on 80+ player modded servers has no right to complain.
I also have to find cars that bug like some players say they do. Never had an issue driving for hours and even having to refill because i drive a lot.
So that's what you were up to yesterday Uncle Joe. So can i have that Gunther around Mogilevka that was missing a spark plug?

Yes, my server runs quite empty, getting it more populated is quite tricky, most want modded it seems.

Our cars seem to stick around for weeks on end, if we don't break them that is. If you consider my test to be flawed, point it out to me and I will run it again in a week or so.

Nice rant. But the person you quoted mentioned nothing of a modded server, nor an overfilled one. So curb your ramblings.

I have not seen this happen on my server.

Thanks for the input, yes, that's what I was doing yesterday The Gunter by Mog was not ours, there are a few other regulars on the server so could be one of theirs, anyway we have built two now, plus an Ada.
