Would you please explain your problem? Try deleting all filters. E.g.: set ping to 0.

when i click on multiplayer game crash without displaying anything from the multiplayer lobby (can't see filter, list or anything else except the stratis map on background)
some times it works perfectly (-10%)

To solve your problem we need dxdiag and files from this folder: "C:\Users\<Name>\AppData\Local\Arma 3 Alpha\"

Can you pack the files in winrar and upload it somewhere please?
When the *.rar will be smaller than 2.097k, you can attach it here. Thank you.

Thx Hanz, and sorry for this poor feedback report.
Here's the files you've asked for.
for your information the exe didn't stop, crash or said anything like directx crash report, i had to stop the process manually.
