Greetings,A month ago i upgraded my previous Dell Inspiron 7577, with GTX 1060 6 GB to the todays G15 5511 with RTX 3060 6 GB. Overall i am very pleased with the design, full rgb 165 hz screen, and of course performance. It handles well all the titles especially the Red Dead Redemption 2 on max settings with 70 fps. First 2-3 weeks i had no issues playing any games, all smooth as butetter but a week ago i noticed that sometimes i experience a huge frame drop lasting 1-3 seconds and then it goes all back again to stable fps. For example from a stable 80 FPS- i get drops to 25-30 with he screen all stuttering and in a moment i comes back to 80. Firstly i noticed this issue in the Red Dead Redemption  2, and i thought it may well be a game optimization issue or even my ultra settings which i have lowered. But to no avail. Next thing was to test other games, and guess what ? I have the same issue even there, in no demanding games such as CS:GO.If i use MSI Afterburner to monitor the hardware stats i notice that during this stuttering the GPU and CPU clocks are NOT going down. So GPU stays at a constant 1900 Mhz and cpu 2400 Mhz (with Intel Turbo Boost off). Dell's hardware diagnostics from the site and downloadable soft such as support assist, showed no hardware issues.My temps during heavy AAA titles are: GPU - 84 degrees Celsium MAX                                                                     CPU- 75-80 degrees MAXI am using a laptop cooler always and of course i activate the G-mode, and fans are running on 100 capacity along with the High performance mode activated along it. So we cannot talk about the thermal throttle here.  I may well be mistaken but it is possible that these issues started after the last 1.20 bios update which i have made around that time. SO what i have tried till today ( with no luck of course  -I tried to downgrade the BIOS to 1.19.0 using the dell utility, surprisingly the issue remained.-I tried reinstalling windows from zero, with all updated drivers.-Tried downgrading the nvidia display driversIt is quite frustrating since, i have never experienced any issues on my previous dell which was far simplier and not as powerful as this rig. And it is very strange that i get this stutters without any visible motive. Please advice on what to try/ to do next. Thank you .
