I am at a bit of a loss here. I have many years experience with computers but am struggling to suss out my problem. I have a 2019 Predator PT515-51. It has had very little use. The only games I have are Steam platform Uboat, Myst and Train Sim World 2 which were giving my around 50fps. In January this suddenly dropped to 10-15fps which makes the games unusable. I loaded the free 3d Mark which again works via Steam and the results are in the picture. I am running Windows 11 which was fine before the slowdown. I have uninstalled the Intel 630 VGA drivers and reinstalled the ones downloaded from Acer the site and tried going back and doing a clean install of 474.xx Nvidia drivers but no difference. My Predator Triton 500 has RTX2060 16gb Ram 500gb NVme standard drive and an extra 1TB Samsung NVme D: drive. I also have Logitech G Hub installed not that I can think this would cause any issues. I run Photoshop, Premier and Fusion360 as well and these seem OK performance wise.  Any ideas would be very helpful as this is pretty frustrating.

    Hi @ Badgersurfer 

    Random FPS drops from Low GPU Usage/Power Usage. It is most definitely a CPU issue... or more specifically an "APU + Chipset" issue. You have to keep in mind that the AMD "A" series APUs are based on the AM3 Athlon platform thus; perform accordingly.

    Sudden FPS drop usually means a bottleneck of the system when some event interrupts another hardware demanding task for example game, which is surpassing the capability of the system. Common bottlenecks can be seen when other demanding tasks suddenly occur on the screen which is difficult for your CPU to handle.

    Well just to let you know I sussed it. Thanks for all your advice. It was the thermal throttling on the GPU that was causing the problem. I repasted the GPU and CPU and used SnowBabe Thermalright Thermal Pad 12.8 W/mk on the rest. Now my gpu sits at about 45 and cpu 65 and everything is running at full throttle again. Also I invested in a KLIM Cyclone cooling stand and that is superb.
