Hello guys, this is an update of this thread: https://robertsspaceindustries.com/spectrum/community/SC/forum/3/thread/intel-12th-gen-cpu-stutter-lag-issues-analyzing-wo Current issue: https://issue-council.robertsspaceindustries.com/projects/STAR-CITIZEN/issues/STARC-32843 We still are having big performance issues with the newer intel CPU series. Time has passed - I upgraded my PC fom 12900K to 13900K and the game is still having the same issues utilizing the P-cores correctly. And yes... 3.18 has still this issue... Many people asked me, how to automate my CPU affinity workaround. I will provide a powershell script with two tutorials: just simple fix (run separetely after launching the RSI Laucher) and an automated script (just run and start the game) Simple fix 1. Open notepad/Editor 2. Copy and paste following: ForEach($PROCESS in GET-PROCESS "RSI Launcher") { $PROCESS.ProcessorAffinity=21845} 3. Save on Desktop as RSI_Fix.ps1 (make sure the file is ending with ".ps1") How to use? 1. Open RSI Launcher and wait for it to appear 2. Go to Desktop 3. Right click on "RSI_Fix.ps1" 4. Select "Run with powershell" Automated (hidden) script 1. Open notepad/Editor 2. Copy and paste following: start "C:\Program Files\Roberts Space Industries\RSI Launcher\RSI Launcher.exe" sleep 5 ForEach($PROCESS in GET-PROCESS "RSI Launcher") { $PROCESS.ProcessorAffinity=21845} 3. Adjust the path to your launcher if it's installed somewhere else on line 1 4. Adjust the timer ("sleep 5") if your RSI Launcher takes longer than 5 seconds to start 5. Save the file as "RSI_Fix.ps1" on desktop (make sure the file is ending with ".ps1") 6. Right click on desktop and create a new shortcut 7. Use this as path (replace XXXXX with your username): C:\Windows\System32\cmd.exe /c start /min "" powershell -WindowStyle Hidden -ExecutionPolicy Bypass -File "C:\Users\XXXXX\Desktop\RSI_Fix.ps1" 8. Set name: RSI Launcher FIX How to use? 1. Double-click on "RSI Launcher FIX" at Desktop I hope CIG will fix this issue with the new intel's flaghsips soon - it's been now 2 generations of CPUs... If this workaround doesnt work for you, check out the thread mentioned at the start of this post. Feel free to post better solutions / workarounds, I will add them to this post. Corn
