fixed Game freezes when I try to select aircraft in MP lobby.

[AJaromir]

For first time game freezes - Not responding. I tried to wait few minutes, but no joy.

This happens since the last two updates.

For unknown reason this crash does not happen every time. It is like 1 out of 5 attemps result in no crash. No matter which aircraft I choose.

hello. the dcs.log is not showing a crash. looks like you are loading a track?

not much in the log to diagnose anything.

What about it? As I have written. It happens when I click on the aircraft in the aircraft select menu. Game stops responding. I can wait 10 minutes but nothing happens. I am loading MULTIPLAYER mission from the multiplayer list of servers.

For the next test I deleted the whole tracks folder and logs folder. Now the game definitely crashed. Here is the log:

I have similar problem. I cant respawn into the plane in the missions I created. this happens about 1 out of 5 times after starting a mission.

New attemp.

Before starting the game the "tracks" and "logs" folder deleted

Tried different server than before.

dcs.log

It seems to help prevent freezing after setting the filter in the aircraft selection to wait 10-20 seconds before clicking on the machine.

you said nothing about loading a track. does this happen with any other server? just trying to help.

Yes. Check my other posts. It looks like this is how DCS load MP missions.

[AJaromir]

I've noticed that TrackIR5 often crashes when the game crashes. Could this be related?

O.k. TrackIR nor any controller have no effect on the issue. I tried to select aircraft in MP session with all devices unplugged, but crash still occurs.

[AJaromir]

As if on purpose, when I try to take a video of the game crashing (by Nvidia App), the game never crashes.

This is how the crash looks like: When I clicked by mouse on A-10CII, the game had frozen with not-responding message. Waiting solves nothing. Tried to wait like 10 minutes.

Here is the full debug log: dcs.log

This is where the freeze happens:

all of the logs show the freeze without a doubt. it is not crashing. i do not see that you said you did a repair. have you tried that?

Yes. I tried to run slow repair.

My personal opinion is the Issue is most probably in the "aircraft select" window. Because every time I reset the filter or switch to another plane, the game freezes every time. But every time it comes back on within a few seconds. It just always depends on the first selection. If that one doesn't freeze, then everything works relatively normally.

@silverdevil

Do you have GeForce Experience or Nvidia app? Looks like once I uninstalled the Nvidia App, it stopped freezing. I have to try it about 50 more times to be sure.

O.k. Now I am like 90% sure it is caused by Nvidia App https://www.nvidia.com/en-us/software/nvidia-app/

I'm not sure if I should start a new thread on this topic.

i had the Experience app prior to uninstalling it and going for the new nvidia app. i have seen people mention the nvidiaware causes troubles in their systems. so maybe. your hypothesis about filtering seems sound. i do not not play much MP. but i do have squadron created missions that are made for MP / CO-OP PvE. i will try one while filtering the AC types.

As others suggested, use the filter. It keeps the freezing down somewhat.

This is an old problem in very busy MP servers. You would also see server wide stutters when players reslotted or joined/dc'ed sometimes.

Servers that switched to only using dynamic slots got around it.

I don't think it's that. I purposely tried connecting to Shadow Reaper's and got to a regular static slot without freezing. As I wrote, I strongly suspect the Nvidia App is doing it. Because every time I've tried to take a video of the game crashing via the Nvidia App, the game has literally never crashed as if on purpose. But when I turned off the recording, the problem came back. Thus, I got the idea to uninstall the Nvidia App, and the problem disappeared. Now I've tried reinstalling it back, and I'm trying to see if the problem has returned or not.

if this is true, you have discovered a very counterintuitive problem.

this is a good observation. i have seen this type statement in lots of problem reports here on the forums. now that i think about it. the stuttering happening when players are claiming different slots sounds a lot like bandwidth usage.

I don't think it's bandwidth, but it could be.

When a player joins a server that is using thousands of slots, I think it refreshes the entire list of slots and players for every single player simultaneously which can cause a freeze.

If you leave the scoreboard or role select open you will notice every single time a player joins, disconnects or reslots, the ENTIRE list refreshes. Score board will scroll you back to the top, and you can see the list of spectating players flicker as it refreshes.

This has been my observation over the past few years at least. ED recently did an optimisation pass on this aspect of the game which helped reduce the server wide freezing quite a bit, but it was a bit of a bandaid on a fundamentally flawed system imo.

This sort of behavior was previously mostly limited to having role select open while in VR, but it's gradually built to the point where it's a problem for flatscreen players, and then to the point where it spilled over into general gameplay.

Bit offtopic: DCS:W sometimes runs well, sometimes it stutters for no reason. 90% of stutters are solved by disabling core parking on my system. But sometimes I have to restart the whole game to get smooth frame rate.

Now back to issue:

After installing Nvidia App back the issue appeared again. But still it can be fluke. I have to uninstall it and make like more attemps to be really sure. If there were people here with the same or similar problem and could try it, it would be a lot easier.

I'm having a similar problem happening right when I should spawn in my jet in MP. DCS freezes for a very long time and then sometimes loads, and sometimes the client crashes. I try the Nvidia app like you suggest... mine has me stumped. Once/If I'm able to slot in, then I'm usually fine for several spawns.
