Verify Game Cache/Delete Blueprint Cache

[Hawk]

It's regularly asked how to delete the blueprint cache and how to verify the game cache. Hopefully this post will make that info easier to find.

One thing you always need to do after installing a lot of new content into RW is to clear the blueprint cache. When you first load RW, on the first launch screen (don't click on START yet!) go to the Tools and Docs tab and choose clear blueprint cache.

The other thing to do is, every once in a while when the game starts acting strange (or should I say stranger than usual) is to verify the game files. Open Steam. Go to Library. Right click on TS2012, choose Properties> Local Files tab> Verify. Yeah, it can take a while to finish, and do it at least twice until Steam doesn't find any more missing files. Hope some of that helps.

I just finished "Verify Integrity of Game Cache" and received the following message when it was all done:

"5 files failed to validate and will be reacquired"

What do I do now? Are the files re-acquired automatically without any intervention on my part? Do I have to give it some time to reacquire these files before I run the Train Sim? Should I run Steam so that it is ready to re-acquire files? Should I clear the blueprint cache right away, or give it some time? I understand that I should also re-run the "Verify Integrity of Game Cache" again, until all files validate properly. Should I do that immediately, or give it some time to re-acquire the bad files from the previous run?

Thanks. Loving this forum. Its good to know that there are so many knowledgeable users willing to share their experience.

The only time I will run the verifiy game cache is after an RSC/Steam screw-up (ahh, update). Then I will run it over and over until there are no more files missing. This tends to take time so grab a cup of coffee or Glenfiddich. I also make it a habbit to clear the blueprint cache everytime I start up railworks.

Hi, Sheppard. I do a verify usually after any update from Steam/ RSC or a new DLC. Also, I run the clear blueprint cache every time I start the sim.

Verify will aquire the missing files for you automatically. I generally run it a few times until no missing files are found. Steam will find and install all the files for you. Basically, all what Blue Light said.

Be warned, some third party add on's like sound or lighting packs may be over written when you verify. Steam puts it all back to default. What I do is use Doc Lisboa's tool, all my stuff in a seperate folder, three clicks and done.

Sorry, two clicks and you are done!

Maybe a link to that tool would help?

On the way:
Reinstall RW3 Mods with 2-Clickz (Basic)

The "Clear cache.bat" (comes along with pack) has been very usefull also, especially after the Feb update, you can clear cache whilst still in-game before load a scenario (no need of exit and restart TS2012).

Cheers,
Doc.

Thanks, Doc. It really is a nice tool. (Oh, I think Ed is watching me like a hawk )

[Hawk]

Doc - Have you thought about adding this to the RWA Library?

(Oh, I think Ed is watching me like a hawk )

No more so than anyone else. I'm always flying high above the terrain looking for prey, as any good hawk would do.

[Machinist]

Yeah, had though, but haven't gone further because I also thought in include medium and advanced tricks, which is suspended so far because DanteInvidia is working in a similar GUI. I'll do it, then. I mean... the upload, not the Windows' GUI.

[peterhayes]

Doc's 'blueprint cache clearer' is a life-saver for me. If you try to run one scenario after another - very often the second or 3rd scenario won't load - for example try running scenarios with thw VR de BR 143 one after another to see what I mean, but using Doc's clear blueprint cache whilst in game means that you can run one scenario after another without having to exit and come back in again!
So if I can persuade Doc to link a "hot key" or one of the Raildriver buttonsmethod of operating clearcache.bat that would be the icing on the cake ( I use Alt=Tab at present to run the bat file.)

Thanks again Doc for these two fabulous utilities.

Yes, Steam automatically reacquires files that fail to validate. This happens immediately if your internet connection is active. How much time it takes depends on the speed of your internet connection and the total size of the files to be reacquired.

I often see forum members reccomending verifying the game cache multiple times in series. I tried that once or twice, but the second report was always that all files had validated, leading me to believe that once is enough. Perhaps a particular internet connection or a particular server might fail to correctly download the files to be reacquired, thus requiring a second integrity check?

[Chacal]

Yes.
A client-server protocol usually has timeout triggers that cancel a request if the answer is delayed for too long, which can happen more often for some users than others due to bandwidth, lag, server availability, line noise, etc.

One thing that everyone needs to take into consideration is: When you connect to the Steam server, it is not a direct connection from your computer to the Steam server. The connection goes through many other servers along the way. A dropped connection or slow connection can happen at anyone of those servers, causing the update to not complete. Hence the suggestion to do the Verify thing more than once to make sure all your files are up to date.

Here's an example of the connection from my computer in north Georgia to the Steam store main page. The ms on each entry is milliseconds.

Tracing route to store.steampowered.com [208.64.202.69]

Trace complete.

The number of servers your individual connection has to go through (hops) depends on your location and the location of the server your connecting to. It could be less or more than shown above, and any server in the list could have a problem, causing a problem on your connection.

Many thanks for the explanation! I gather that it explains why my attempt to order the Cab Forward and the GE-44 has been tied up all day long? Ain't life in the lightning-fast computer age a blast??????

That may very well be the Steam server itself; just too busy to handle the traffic.
