Core simulator based engines can't really be used as a basis of simulation, but I believe your findings are correct. Over the last few months of testing for the AC44 debut, I have been finding issues and making adjustments for the car physics.
I believe they are overweight and drag set too high. I will be adjusting these values and releasing patches for all of them soon. I'll also be addressing a mentioned consist messaging issue with the 4750s.

I have performance issues with 6 locos in a train (NS-Bundle).
This results in slideshows of 0.5 fps in some situations.
This might be due to the enhanced particle system (virtual railroads once wrote that that in TS a resonable amount is 6 different systems) or scripting.
The only thing I have found is in the logmate:

It would help if you could specify the circumstances more. How long of a train, what type of cars, what provider, what route, what section of the route, what weather settings etc..

I used different consists in a quickdrive with AI traffic, thats not the ideal system to compare some situations.
To have someting better I will create some simple scenarios until tomorrow and report my observations.

Here are my scenarios for testing:
From Waynesburg to Bailey Mine (PennCoal or Norfolk Southern Coal Route).
The player trains to test are:
a) 2x JR SD40-2 NS
b) 2x JR SD40-2 NS + 100 Coal Hoppers with the hoppers from the Penncoal Route
c) 2x JR SD40-2 NS + 100 Coal Hoppers with the hoppers by JR (JR_100TnHopper)
d) 6x JR SD40-2 NS
e) 5x JR SD40-2 NS + 100 Coal Hoppers with the hoppers from the Penncoal Route
f) 5x JR SD40-2 NS + 100 Coal Hoppers with the hoppers by JR (JR_100TnHopper)
In every scenario there is a train with 44 hoppers and a ES44AC from the route starting from the next block.

Results:
a) (2 locos) up to 30 fps at start
b) (2 locos + 100 PC-hoppers) up to 21 fps at start
c) (2 locos + 100 JR hoppers) up to 20 fps at start
d) (6 locos) up to 16 fps at start
e) (6 locos + 100 PC-hoppers) 19-21 fps at start
f) (6 locos + 100 JR hoppers) up to 14 fps at start

Test e) has been taken place after a complete restart of the computer in the last run. Nothing changed. Betweeen the other tests the TS has been restarted.

I am happy that my result do not completely confirm my misgiving from two days ago, but the performance is not outstanding.

The difference likely result as in my quickdrive you have a lot more rolling stock in the scenario and/or I have too many consists TS can choose from (>200) and the prossibility that not all consists are fault free is obvious.
I want to apologize not to confine myself from the beginning to a simple case.
That was not very wise of me.

I'd say that the limiting factor in this case is the graphics card, as everything else seems pretty good. With my 1070, I have about 15-25 better FPS than what you're experiencing. Specs are otherwise mostly the same.

I'm a little confused. Two SD40-2s and a hundred loaded hopper cars. You're lucky if you can get it started and it sure isn't going to pull up that grade from the mine. !**conf**!

I checked this, too *!!wink!!* :
With 2 SD40-2 and 100 EMPTY coal hoppers I got in run8 26mph minimum (25mph allowed!)
It is not very usefull to carry coal to a mine, isn't it ?

It must be your video card. I was getting 48-55 FPS with the 2 coupled and 22-40 FPS with the 6 coupled..

Buzz, there is a physics change regarding the NS/CR SD40-2s, that should release once we are out of the red !**duh*!!

I seem to have come up with a simple fix for the time being which will fix those with issues on grades for at least the UP units. I have not played around with the NS units as much but suspect it will work also. The core simulation / scripting for these units is different from anything anybody has put out and really well done and uses completely new variables the end user cannot modify like any other DLC anybody has produced. These units are still reading from the TractiveEffortVsSpeed.dcsv and TractiveEffortVsThrottle.dcsv files however they are not necessarily using the data the same way as other developers units and DTG's DLC from my experimentation. It is almost like the data is read as a maximum threshold which was set way too low. The simulation file is also the same with some pretty wild far out numbers. I tried setting my own values and borrowed some from other units and experimented for several weeks off and on comparing my findings to Al Krug's train force calculator. My goal was simple, get a single unit to pull 1255 tons (13 loaded boxcars) at 10 miles per hour up a 2.75% grade with 14 degree curves in run 8. I was able to achieve this with a speed of 10.1MPH versus the default files with the train stalled on the grade. After much experimentation I settled on the attached values which are copies of the DASH9 and SD70M-2 dcsv files. Installation is simple, backup your simulation folder and copy the two files.
