Hello. I have had FPS drops for a couple months now with PUBG and checked on what might be the issue. The FPS usually stays around 50-90 but after a game or two, it drops down to 10-15 in intervals. The lag lasts for around 10 seconds and then goes back to normal. The intervals varies every 5-7 minutes, but can even go down every 2-3 minutes if I keep playing. It is both game lag and audio lag.
I ran Nvidia Inspector and Core Temp on my second monitor while playing. When the lag occurs, the GPU Clock drops from around 1300 to 300 and the temp goes down from 56°C to 43°C and then back to normal. Both Power and Voltage on the GPU also goes down. The CPU however has all cores at 100% load and temp reduces from 58°C to 41°C. The FPS-drop then repeats and I have to wait. The weird part is that it recently started happening to me in CSGO which runs at around 200-300FPS, same results there as well.
I have cleaned my computer and replaced cooling paste without any success. The last option I had was opening the side of the computer while playing, and the intervals seemed to slow down then, however the dust started stacking up so I decided to just keep it on. I was going to replace it with a better graphics card, but seeing that it might be a CPU problem, I might have to get a new one as well. Hope anyone can help.
