Wheels not showing. Performance issues.

[nicky9499]

Hi people.

I've got a session which starts in a very dense area. Regardless of control method, when I pan around the locomotive, the wheels on the entire train (and pretty much every other train except their locomotives) disappear into thin air. These do not reappear for the rest of the session.

I do suspect that it has something to do with the severe density of that portion. What are some things I can do to improve framerates in such situations without affecting the overall feel?

That aside, are there any known causes for this disappearing of wheelsets?

Cheerio,
Nicholas.

How much RAM do you have in your computer?

Which version of TS?
What is the speed of your CPU?
How much RAM?
What video card do you have? How much RAM does it have?
Any other programs running when you run TS?

So many things can affect how well or poorly TS runs. It's a huge drain on resources, as are most games like it.
I have just ordered my video upgrade. I'm going from an NVidia 6800 with 256Meg to Nvidia 9800 with 512M.

Hmm. These shouldn't be too bad:

Asus M2N68VM
AMD Phenom X3 8450
HIS IceQ4 HD4850
Aerocool 550W
WD Caviar Black SATA2 500G x3

Such a problem has never happened before, it's baffling me.

Cheerio,
Nicholas.

I had the demo of TRS09 and several items were missing wheels. If you have a copy of 09, the intermittent wheels might be a wrinkle that hasn't been ironed out yet.
Unless it can't be fixed, in which case it's a feature.

No. That is not likely. The locomotives in question are all custom ones from third party sites and the rolling stock have run on the same route and session before without any problems. Also, the wheels do not disappear intermittently - once they disappear, they do not reappear for the rest of the session. Initially they show up fine, but zoom in and pan around then they vanish.

I've also discovered a new problem: after passing a definite point on the route, the train starts to get stuck, literally. Under DCC mode, it will pause for a second (the speedometer showing 0mph), then jump back up to speed (x mph) for another second. The "stuck" duration increases until the train completely stops. In cab mode the wheels just grind against the rail (evident from the screeching noise) and also get stuck and unstuck. Like there's some invisible hand holding the train back.

These problem all discourage me from continuing building the route any further as there is no point because the trains cannot run properly.

Do you have the 'Options - Tuning - Train Poly Count' slider from the initial screen maxed?

Wheels usually fall off when there is an issue between the number of polys to be drawn and the available resources. You may just have too many trains in the yard or too much content in the background in which case the fix is fewer trains or less content...

It's been solved - by deleting the entire session and making a new one. I suspect the problem laid with some faulty rolling stock. Performance still takes a hit in the starting region, despite me closing all other background applications and setting the Trainz.exe process to realtime priority in Task Manager. Thanks for all the suggestions.

Cheerio,
Nicholas.
