I have run into a rather strange problem. Yesterday I did around 10 hours of work editing a video, its a fairly hefty project with around 45gb in assets. I was editing with no playback or performance issues what so ever, yet today I have loaded up the project to pick up where I left off and i'm suddenly dropping 1000's of frames per minute.
CPU: Intel Core i7 10700F Comet Lake 4.8GHz (Normal 2.9GHz*) 16 Threads 16MB CPU
Memory: 32GB DDR4 3200
Graphics: 8GB 3060ti
SSD: 500GB NVMe M/2 SSD
Motherboard: Intel B460M chipset Running latest version of PPCC
As I said the project was running perfectly yesterday, full res playback, very little render times etc. Today it has become unusable. The project is runnning from an external drive so I opened the project on my 2015 Macbook Pro and it ran with no problems (I had to lower the res to get smooth playback on the MB but lowering to the same res on my PC still drops the same amount of frames).
I've tried every solution the internet has thrown at me for fixing dropped frames in PP but none have worked. I've reinstalled & tried older versions. I've ran diagnostic tests on both RAM and GPU, no issues. All drivers are fully up to date. I've opened some huge 3D projects I have in Blender and they still run perfectly. I've even ran Call of Duty with the graphics maxed out at 170+ fps with no issues. It seems to be an isssue isolated to PP because it also drops huge amounts of frames on tiny projects that have less than 200mb worth of files. Rendering the final output still works perfectly.
Not sure what else to try at this point so any help is much appreciated.
Thankyou in advance.

Is the external drive a standard hard drive instead of an SSD? If so, you could have passed the capacity threshold for high-bandwidth performance. It varies from drive to drive, but the general rules of thumb for a standard drive is 80% capacity (which you can usually push to 90% in a pinch). It's really as simple as you go above that threshold and bandwidth drops while if you stay below it bandwidth remains fine.
