I played race w/o disconnect freez and Stutter at this race.
I think this freeze was caused by car mods (especially UPGRADE).
Because I've raced on this cars many times but never experienced disconnect freeze.

I did to retry to use plugins at multi race.
Also, I had many stutter.

This is my plugins.
Z1 Dash, Crewcheif, DAM and etc... Which one is bad?
Thank you.
@AirplaneRider @yashiman @Alexandr Meshkov @geepee and to all other people having stutters, can you try removing ALL the 3rd party plugins and then check if the stutters are gone?
Also please could you test with RealtimeLogging set to 1 in the player.json file?

I tried your suggestion that 3rd party Plug-in's uninstalled.
I feel certainly stetters (short time lag) better than before. (But in the race, I lost FFB 2 times.)
And I crashed suddenly When other driver conection lost.
Actually ,this issue has existed before 2016.
rFactor 2 Issues
(Maybe this problem has occurred since the end of 2015.)
I thank S397 members. Please do your best in the future.
私は4thworld氏の「サードパーティー製プラグイン」を削除するという提案を試してみました。
確かに、スタッター(ショートタイムラグ)は、減少したと思います。(ただし、レース中に、FFBが2回消えました)。
そして、他のドライバーのconnection-lostが発生した時、私は突然クラッシュしました。
実は、この問題は2016年以前から確認されています。
(多分、2015年の年末頃から発生しています。)
S397のメンバーにはいつも感謝しています。今後共がんばってください。
