Rider for Unreal Engine keeps caching my project every time i start it

Every time i open Rider for Unreal Engine it likes to cache my whole project again. This uses 100% of my ram and cpu (32gb ram and i9-9900KS cpu)

 

Is there a way to turn caching off or limit it in some way? I wouldn't mind it's caching but my whole pc is unusable during the few hours it takes.

Hello,

Rider is definitely not expected to behave like this. Would you mind creating a support ticket for this case? Please collect Rider logs as described here and attach it to the ticket. Thank you in advance!

Hi, it happens to my end every time I switch branches. Right now my only solution is to close Rider before switching branch. But if I forgot to close it, cache will be invalidated and recache.

 

Is there any way to disable this process because it is awfully slow on large projects.

Hi Jeff Jadulco,

 

Please collect the Rider logs after switching branches via Help->Collect Logs and submit them as a part of a new support request (Help->Contact Support).

Me too. It happens after I upgrade R4UE to 2020.3. It takes too much time and memory.

Hi 1119369173,

Would you mind trying the recently released Rider for Unreal Engine 2021.2 and letting us know if you still experience this issue?

I want to bump this, even with 2021.2, it takes a good 5 minutes every time I open rider before I can do anything. Im on a 7700HQ with 16GB of RAM and every time I open rider, it takes ages to invalidate and reanalyze unreal engine source files - which it does on every opening.

This is more important to me on my laptop which has limited cpu power and battery life when compared to my threadripper desktop.

Hello Marstaik,

This behavior looks like a bug. Would you mind collecting and sending us some additional information that we could use to investigate the issue?

  • Use Help->Diagnostic Tools->Choose Trace Scenarios action and pick CppCaches scenario
  • Reproduce the problem
  • Use Help -> Report a Bug shortly after reproducing the problem. Agree to attach logs, leave a short description of this issue or a link to this thread and specify the engine version you are using (for example, UE 4.27 build from Epic Games Launcher or UE 5 build, branch ue5-main from GitHub).

Let me know if you encounter any issues. Thank you!
