I cannot play listen server / client in PIE

Hi,
I’m having an issue with UE 4.11.2 - 4.13.0 on a Win 7 with a 980 (updated drivers)

I can not play listen server / client from PIE. UE4 becomes completely frozen. I have to open the task manager to shut down the program. If I build and manually add the listen server and client commands to shortcuts everything works just fine, it’s playing from PIE that doesn’t work. I know it’s not my project because I also created a stripped down UE4 default third person project and it locks up when trying listen server / client combinations.

If I play as listen server PIE works until it starts to load the client, as soon as the loading window appears UE4 locks up and the client version just plays single player.

If I play as client the listen server loads up just fine in its own window but UE4 never connects, is locked up, and never shows.

I tried looking for crash logs but can’t find any, I assume because UE4 hasn’t actually crashed.

I’m looking for any help or thoughts or logs… or something.

Thanks
Russ

(Amateur here, but…) Since it’s a very popular feature that is used by a lot of people, it is almost sure that the problem is the way how you are trying to do it. Could you give us some detailed print screens about the problem and/or a link to the stripped down project (shared with Google Drive, or anywhere else)?

Glad to hear it! Then I guess mark yourself and solving answer in this thread and good luck in the future!

Hi CrimsonHawk. Thanks for the input I did figure it out finally…

It was my graphics driver. I rolled back about six versions which required the install to be a “clean installation” and that worked. So I started moving forward version by version expecting one of them to break it, but every installation was a “clean installation” not the express that I would typically use. Then I found a few Nvidia threads about other issues when not doing a “clean installation”

Lesson learned, always clean install.
