    Cool Direct comparison - head to head

    I hadn't really tried comparing Open Rails to MSTS before because it's not really ready - signals and AI traffic need to be activated to actually find out if any given activity works better or not. Here's one place where I CAN do a direct comparison, Bzak yard on PO&N 10. No signals or AI traffic involved, just a moderate sized double ended yard. As many of you know I always thought huge empty yards didn't look realistic, keyword railroad TRAIN simulator, not railroad track simulator. So I fudged around MSTS limitations with "static trains":

    https://www.trainsim.com/vbts/showth...-Static-trains

    Seventh pic in that yard is Bzak yard when it was still unfinished, fake trains on fake tracks to get around MSTS bugs.

    So let's do some destructive testing ( FIRE IN THE HOLE! ), open Bzak0800 in the activity editor, add real loose consists to the six real yard tracks, see what explodes.

    In Open Rails 360 that looks like this;



    Hmm, not too good, only 12FPS. So let's see how MSTS handles that;



    I think we have a clear winner.

    Jim,
    Your HW specs would be helpful in the discussion, as well as the Debug HUD showing number of primitives. I'm sure different systems will have widely varing abilities to handle scale you're driving towards. (Pun intended)

    Wink Eeek!

    Oh sir, I couldn't possibly show you my primitives, what would people think?

    Another test, this one I lamed down a bit so MSTS could actually run it without choking. Shadows off in both ORTS and MSTS, distant mountains in MSTS disabled cuz ORTS don't have distant mountains, everything else in both sims cranked to dat's all dey is and dey ain't no mo'. Full screen 1280x1024x32 for both.





    Near as I can tell that's a fair comparison, altho there seems to be a bit more distance fogging in ORTS all the objects and trainsets are displayed. Anyone wants to try this, for the default Marias Pass download and extract the zip, copy to \Train Simulator\Routes, run the WhitefishORTS activity.

    Not so fast, pal !

    This in MSTS still beats whatever, especially the distant mountains I have helped you with !

    Wink Izzatso?

    You missed the point, with ORTS not having signals yet any comparison in an area with a lot of signals would be unfair to MSTS since MSTS is handicapped by having to display the signals. Same thing with distant mountains, ORTS don't have distant mountains yet, so adding the extra weight of distant mountains for MSTS to carry makes it an uneven comparison. Idea here is to see what the new kid can do when carrying the exact same load.





    ORTS wins here, if I enable distant mountains in MSTS the difference in FPS would be even more since MSTS would have to process more data.

    Does seem a touch weird, though given the also high frame jitter I'd guess that the data (for all three values) either hasn't settled or is generally being unstable. If there are loads of sound sources, like wagons, the current release can get pretty jittery and it could just be that.

    Perhaps with your computer.

    Did you see the 34 FpS in my MSTS screenshot with everything set as MAX and Distant Mountains on ?

    With distant montains not showing in ORTS I get these FpS below.

    Default What is the sound of one SigmaTel clapping?

    Odd thing but in computer games the sound card can sound just fine, but affect the video display in strange ways. Back in the Days of DOS and Dinosaurs I had a 486 with onboard video (state of the art at the time) and plugged my old original 8 bit Soundblaster in. Gunship 2000 had an odd glitch where the helicopter "weathervaned", rotating it into the wind whenever realistic wind was turned on. Microprose tech support had no clue, but when I replaced the old sound card with a 16 bit Soundblaster II, it eliminated the problem.

    Consequently I suspect many of my video problems with this system could be cured by replacing that cheap onboard SigmaTel sound chip with an actual sound card. Note the numbers in the other post showing Bzak yard in explore route mode, all those cars are fake "static trains" and therefore have no SMS files to load and process.

    Missed your post, Otto.

    "With distant montains not showing in ORTS I get these FpS below"

    Okay, now turn off distant mountains in MSTS and take the same screen shot, see what the FPS difference is.
