Monogame (recent releases) question - Engine performance

[qballbandit]

Hello,

I have used MG for sometime, though fell away from staying with the more recent releases. I have be running very stable on the older v143.
Over the last several weeks I have tried the newest releases up though v162.2, and notice that a couple of the engines that I frequently run behave drastically different. One, and ES44AC needs twice as much throttle to run at track speed now. Another a ET44AH barely gets moving then several yards out just goes idle, even if in run 8.
Yes, these are leads in front of second unit and cut of cars - all perform fine in V143.
I tried removing include files for Engine physics, but made no difference.
Is there something in the later versions of MG that effect engine performance? Other SD40-2'a and GP38-2 that I run seem fine.
Not sure where to start investigating, so appreciate all suggestions.

Thanks very much,

Neil

Hi Neil,

Same with UNSTABLE version - 100% concur. I'm testing with my project Alco RS3 using Gerry's advanced physics.

I need like 50% throttle just to keep a solo locomotive moving.

Something has changed.

Regards,
Scott

( To Both Posters ) --- Which model physics are you using....Advanced or Basic? Switch physics models and see if problem still occurs.

Hi Gerry,
I wrote this above; "I tried removing include files for Engine physics, but made no difference." is this what you are referring to?

[R. Steele]

Go to Options on front panel -- then to Simulation tab --- should be two different check boxes...one for Advanced Adhesion Model and one for Simple Controls and Physics....if they haven't been eliminated or moved.

Also your log will show which model physics you are using --- Look for this line >>> UseAdvancedAdhesion = True

It is really bothersome that the physics portion of ORTS keeps getting messed with. It is time to leave it the hell alone, and move onto more pressing matters, such as more than one cone of light!!

Honestly, I would love to see the current MG move forward, but I have noticed, half the locomotives, cars, and routes will not work, including winter scenes on the MRL Mullan Pass from TS.

ORTS 1.5.1 I still thankfully have installed on my system, and probably is the final decent "stable" build in my opinion, but unfortunately, seeing the direction ORTS is going, with the constant breaking of physics, and even save modes, I see myself losing interest and going elsewhere, and I am afraid this is also going to end up pushing others away too with the constant breaking, and end users constantly having to rebuild their stock over and over and over again because something that wasn't broken, keeps getting toyed with and screwing things up.

"Working as intended" just isn't suitable for most of us.

No problem here with winter scenes on Mullan, everything has always worked as expected...( please troubleshoot your install for problems )
Also I understand your frustrations with some changes, however, at this particular moment that is of little concern in this thread...I am trying to gathering information about the current problem....it will probably need some developer to spot the thread that also has knowledge of any code changes to the diesel power portion of the code....I am woefully ignorant of the code. I looked at all the changes made recently and cannot spot anything obvious.
...and we are not talking about the perennial problem of light cones ( which we all can agree on ) ....please Shawn....try to not hijack this thread.

[CSRX]

Sorry Gerry, I'll refrain from any criticism towards ORTS. I often forget that if it works for someone else, it must be something I am doing wrong myself, even though several others have had these same exact issues.
Not exactly hijacking the thread, when I specifically stated it is time to move on from breaking the physics with every single release. Gets tiresome having to redo everything we have, because it all worked well once, but a new update makes them unusable or act extremely silly. I understand you are a huge supporter for ORTS, but it's time to allow others to come in and let the developers know these problems, rather than play moderator and zap away whatever YOU do not agree with, just because everything works for you.

Pontificating about the doom of Open Rails is not going to do anything without specific, actionable feedback. Where are the log files? Engine settings? The screenshots showing before/after? Output from the Shift + F5 debug HUD showing the values in use by the physics system? If any of yall actually want things to happen then more information is needed than vibes and feelings.

Hi Neil,

I have noticed the same.
I am at the point of turning advanced adhesion off, as it seems to getting weaker by the version.
The issue comes from the unstable to MG.

No matter the version restoring from a save leads to almost a broken physics engine. Engines from basic MSTS eng files to the newest .inc files of NAVS and TS. When I asked about it i was told basically nothing. Youtube video showing the problem linked. This was broken a few versions ago. Almost like a arcade game. Especially when game save and take screenshot periodically crash the game.

I'll try the Adhesion suggestion - turning it off, and see if it lends any improvement.
This, quite honestly, is the first issue to creep up for me and my configuration of ORMG. I love playing the v143 that works for me, and the ability to infuse ReShade into the mix. I appreciate that Carlo has taken things in a slightly different direction, and I appreciate how far the OR team has taken us away from straight MSTS.

I also appreciate the suggestions, and will report back on Wednesday if any improvement was gained.


edit: so, sooner than I thought. Toggling the options made no difference. Attaching ORMG log and a copy of the eng file. This engine will barely move, then stop completely, then shut down the engine. I noticed in F5, the second BP reading starts dropping from 90, and the Flow increases. In v143, neither BP drops. Not real savvy on this stuff, so looking for better minds to provide input.

Hi Folks,

Turning off “Advanced Adhesion” fixed my issue. Someone must have treated the rails with gorilla glue - 😆.

Advanced Adhesion appears broken.

Glue on the railroad tracks? Did someone spill a few amounts of glue on the mainline??

[qballbandit]

I'm happy for you, Scott....not so much for me. Turning that option off had no effect on my ET44AH.
The first picture shows that after releasing train brakes, the flow continues to rise, and the BP PSI reading continue to drop.
2nd pic is trying in run 8, but dead stop.
The 3rd pic shows one of my ES44AC's running full notch 8 going nowhere.
If I sit in these engines and wait before throttling up, after several seconds, it sounds like they go into emergency - though they don't. There is a long air sound that plays, similar to Emergency.
