Until now version 2.7 ran flawlessly on my rather outdated rig.
After updating to version 2.8, an otherwise fast rendering "2 minute fun ride of river run challenge" ends in heavy stuttering, with even the windows desktop included with massive CPU utilization spikes.
UPDATE: I let "DCS-Update-Witching-Utility.exe" witch everything, and let "DCS Updater Utility.exe" repair, clean and update. The fps-drops are gone, the simulation runs fast again without any lagging.
UPDATE2: The same symptoms re-occurred, only 20 later minutes into the simulation. Therefore I tried the stable 2.7 version. Here I got the heavy lagging and stuttering like in 2.8 !! So I reverted the to "522.25-desktop-win10-win11-64bit-international-dch-whql.exe" which is the NVIDIA driver version right before the latest version (526.47). With this older driver I did a "river run challenge" and a "case 1 recovery" without any issues. So maybe the graphics driver is also an issue or even the main culprit...
UPDATE3: Close, but no cigar. The stuttering came right back 1h after play. So I did a complete reinstall of Windows 10, this finally solved the problem. After 4h of testing no such problems. NVIDIA-Driver-Version: 512.15 (came right over Windows-Update)
