So lange ist her das ich was geschrieben habe...
Anscheind gibt es bei 1803 nen Bug mit Memory...
Habe die schritte durch geführt und es ist nun weg.
Hier mal ein Auszug aus dem Forum...das Problem ist weit bekannt :
I have tested this thoroughly and it is 100% the cause of my stutters on the creators updates (especially noticeable in games like BF1).
Once the free memory is exhausted then performance takes a big hit, games with heavy caching like BF1 suffer horribly. The only way I could fix previously was restarting the computer (thus clearing the memory), which explains why it was only happening after a while and not on a fresh boot.
I have a permanent solution that keeps memory free at all times. I don't know what MS changed, but this didn't happen on 1607.
This totally fixes my system stutters on the creators.
Download EmptyStandbyList and put it somewhere where you won't move it
Empty Standby List – wj32
Right click > Properties and select Run as Admin under compatibility.
Open Task Scheduler > Create Task on the far right
General Tab (give it a name). Under security options > Change user or group > Advanced > Find Now > go down and choose SYSTEM (important to make it run silently in the background). Tick 'Run with highest privileges' and 'Hidden' at the bottom. Pictures here
How do I set a Windows scheduled task to run in the background? - Stack Overflow
Triggers tab > New > On a schedule > One Time. Tick repeat task every 5 minutes (possibly excessive but it causes no issues). Also choose 'for the duration of: indefinitely'
Actions tab > Start A program > Point to the EmptyStandbyList.exe file.
Done! Standby memory is automatically cleared every 5mins.
I hope MS will come up with a fix, but if you have a similar issue/performance degradation over time - try this. Many on the nvidia forums have said it also fixes their issues.
