ich bin nun schon im Jahr 2079 bei Train Fever und so langsam wird das Spiel unspielbar, da es sehr oft ruckelt und ich nur noch mit 7-10 FPS spielen kann. Verringere ich die Auflösung auf 1920×1080 läuft es wesentlich besser, allerdings sieht dann alles verschwommen und verpixelt aus. Deshalb kommt diese Auflösung für mich nicht in Frage.

Mein System:

i7-4790k
16GB Ram
250GB SSD
GTX 970 4 GB / R9 290X 8GB
Windows 8.1 und selbstverständlich alle Treiber auf aktuellem Stand

Während die GTX 970 eingebaut war, konnte ich sehen, dass die vollen 4 GB Speicher belegt waren, was mich auf die Idee gebracht hat, eine Grafikkarte mit 8 GB könnte das Problem lösen. Nachdem ich nun die R9 290X mit 8 GB eingebaut habe, musste ich feststellen, dass laut Anzeige Train Fever nur ca. 2,3 GB des Speichers nutzt. Wie kann das sein? Sind beide Grafikkarten “zu langsam” für Train Fever oder stößt das Spiel an seine Grenzen?

The game is known to have performance issues. We have an entire thread on it on these forums : /forums/topic/req-multithreading-performance-issu-large-map/ . Unfortunatly the thread is placed in the wrong category (General discussion instead of support). To put it simple: the game engine has a design probblem where it only creates 2 threads. 1 for the foreground processing and 1 for the background stuff. When your game has advanced enough and you have a lot of tracks, roads and vehicles the second thread can’t calculate fast enough and can’t supply the first one with enough data.

If you would like to know more about the technical side you can read this german topic on another site: http://www.train-fever.net/index.php/Thread/2135-Was-macht-TF-Intern-und-warum-es-ruckelt/ . We are hoping someone from the developers will respond to these problems and we hope that this issue will be fixed in the near future.

@Blokker_1999
Thanks for your informations. This problemes i have also since the mid of 21th century. So i understand that the only way to solve the problem is to wait for an update. 🙁

I created similar threads on the performance in the past too:

Performance Issues – Decent Spec Rig.

Are we likely to see any additional performance improvements?

Below is a reply from Basil I received after sending a test file with a number of test scenarios to compare performance, around the time of the second thread above.

Thanks very much for the detailed measurements and explanations.

I’ve re-done the measurements here with an Intel i7-3770 CPU with NVIDIA GeForce GTX 660 graphics card. My system should be slightly slower than yours.

I set the same graphics settings as you and played with 1920×1200 resolution.

Results are very similar to yours. My Fps (for your measurements 1-15) are proportional to yours. Most of them are simply 10% less than yours. So the behavior is as expected (however note that your system may be faster without Afterburner or Fraps running of course).

This said, let me briefly explain the situation.

You are right, the game could/should run faster, especially with multiple windows open (PIP).

We are working on this. You can expect improvements in the near future (however not in the next days / weeks). Here is our near-future-todo-list:

– Make PIP rendering less expensive
– Display PIP windows more intelligent (e.g. do not show 10 windows when buying 10 buses, as you suggest)
– Reduce CPU load (i.e. compute paths of all people / cars / agents not on the main thread / core. Use at least on more core for that. At the moment every time a person leaves a building, the shortest path to the destination is computed, and this is very expensive when having 10’000 persons)
– Make “end of month” CPU calculations faster / less blocking

Until then we can just suggest to not have multiple PIP windows open and to play small or medium maps if you are very “fps-sensitive”.

Thanks again for your efforts and best wishes,
Basil
——————————-

Until then though, the game is on my digital shelf.

Also, the other changes will make a huge difference during gameplay where the FPS drops drastically when doing something like buying 10 new vehicles.

I guess we will have to wait and see what they do or don’t have up their sleeves.
I also suggested something like:

Add a new settings option for Civ Simulation Level.
High: Civ’s 10,000. Scale of Ticket Prices – 100% (as it is now)
Medium: Civ’s 5,000. Scale of Ticket Prices – 200%
Low: Civs 2,500. Scale of Ticket Prices – 400%

to reduce the load from this particular area, fudging the numbers if you like (SC style)

Thanks for sharing the idea. I understand..

However, I think this is more a “emergency solution” which we only make if it’s really impossible to optimize.

We are very confident that we can optimize it so that this switch is not needed.

Best,
Basil
