Increasingly long Spline Load Times as your session runs?

It can take up to 30+ seconds for Splines to load after a few hours running my session.

I have Trainz V-Sync set to 'None' and video card V-Sync set to 'Fast' on a RTX-2060s card. (CPU at ~25% and card at ~80%). This gives me a near perfect stutter free display even when fast Roaming/Jumping across the game world.

I have reported this to N3V support via bug report. Their 'fix' was to change video settings!
(ALL other video setting combinations produce noticeable stutter to a greater or lesser degree on my PC.)

I have found the 'Driver Message Display' somehow causes the problem on my PC for the 'None/Fast' configuration.

NOTE: 'Driver Notifications' in 'Display' menu drop has to be ticked.

Toggling the Driver Message Display' to 'OFF' will bring load times back to near startup delay level.

Toggle 'ON' and the Spline load times jump back out.

I still run with 'Driver Message Display' ON but I toggle it when I move between trains.

Hope this helps someone.
 
Hi ricomon35,
I am referring to Track, Road, Bridges (road and rail), Fences, Powerlines and Tree splines. I do not have any Grass splines.
In short, anything that is installed the same way as track splines.

I have the same problem, that is why I have not released my route yet. I will see if the message off works. I thought it was TRS22PE that I am using.
 
Hi there,

I have had the same problem,but when trying your settings on Vsync low and fast on the video card, I experience a massive improvement. SO THANKS FOR THAT.

Less stutter and quicker spline load times.

Thanks for sharing further performance improving setting.
 
This sounds similar to problems I and others are having.


Scroll down to my post to see why I think it's a memory cache problem, although others may disagree.

You didn't mention what version of Trainz you are using but I'm guessing it's Trainz Plus. My workarounds:

1. Save route and session, exit Trainz, restart the computer, restart Trainz, load the route and session.

OR

2. Save route and session, exit Trainz, don't restart the computer, restart Trainz, load the route and session.

I suggest you try at least #1 and see if that solves the problem. If it does, you at least know it's not a hardware or video settings issue.

Which GPU do you use? Can you elaborate? Thanks.
 
I use an nvidea geforce 1070 with 8 gig memory in an 16 gig i7 machine.

I set the values you mentionned and got a better result. Less stutter, more splines loaded, a longer view in the distance and less need to press the PAUSE key to force a screen update.

Cheers

That GPU is your problem. Wayyyy under powered for Trainz. I recently bought a an RTX 3060, and I still find problems, LOL.
 
I have a GTX 1060 3GB and I can run Trainz 19 and 22 fine. How old is that GPU? I had to buy a used gaming computer on ebay for $445 that has Windows 11, RTX Super 2070, 16 GB RAM, i7 10700 in order to run this amusement park building sequel Planet Coaster 2 which has higher requirements than the first one. My current computer with Trainz on it has Windows 8.1. I guess everyone has moved on to Windows 10 or 11, RTX cards, HDMI monitors instead of VGA. Then I found out that the computer from ebay doesn't have any VGA ports, VGA is analog, so I had to buy a used HDMI monitor on ebay for $35, I could have got an adapter, I have two VGA monitors, one was my late mom's, she passed away June 14, 2022 in the hospital and her computer is an i3, way underpowered for gaming.
