if drops like that occur on laptops, especially if these just started to occur recently and the machine is already being used for quite a while, this sounds like there is some throttling on the CPU going on which might be causing that. I don't believe that lowering your settings will affect it in any other way, than decreasing the frequency of these drops happening. Have you tried to open up the laptop and to clean it up from dust and dirt? How old is the unit? After 2, max 3 years I would also recommend changing the thermal paste on the heatsink.
Hi, thanks for your reply. I ended up solving this and youÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢re absolutely right, it was thermal throttling. I opened up my laptop, cleared up all the dust using compressed air and the temperature went down immediately, as well as my performance going up. I was going to re-paste the CPU but the screws around it were a bit complicated so I left it for another time. But yes, all good now
