file load error

[pikkie walonie]

Hi Everyone,
My savegame will not load, due to the following:
File load error: invalid checksum: iostream_category error.
I cannot find the answer in other posts.
I have iOS X with graphics Intel HD 4000
please help?

Even if you'd get it running, you don't meet minimum requirements for this game and would not have fun playing. I used slightly better integrated graphics for some time in the Train Fever predecessor and had a lot of trouble.

@Thork: thank you for your reply!
to be honest, i played a good few hours on different savegames on low settings..
So running the game seems OK.
Its just the loading of the file that seems to be the issue.
Do you think that is also caused by too low system requirements?

TpF really does not require a powerful GPU, but I find it hard to believe the game would run fine for all but the most basic/smallest setups, at least judging by my personal experience in Train Fever with a HD 4600. Are you sure you don't have another dedicated graphics card?
However, if you're fine with the performance, and the error only happens on that save, I could think of a couple causes, but that is just guessing...

An error in the programming that causes some false/unexpected/corrupt information/handling.
An error occured while (or after) saving the game and therefore some information got corrupted.
Invalid/corrupted file/s required in that savegame (changes in a mod).
Insufficient hardware/memory to load/process all the information present in that savegame.

My personal guess is that the savegame includes too much information that the game tries to stack into (unavailable) VRAM, runs out of it and therefore crashes. It might have worked while playing because some of that information got shifted to RAM instead of VRAM.

You could try to allocate more RAM for virtual VRAM in the BIOS.

You could also try to validate game files. Rightclick TpF in the Steam-library -> local files -> verify integrity....However, I think this is unlikely to solve the issue if it only happens on that savegame.

You could post the contents of stdout.txt and stderr.txt after trying to load the game: "\Steam\userdata\<userid>\446800\local\crash_dump\"

You could also contact UG directly, but they might just point to minimum requirements. www.transportfever.com/about/contact/
