Getting FPS drop in games

Lofty · May 24, 2021

About a week ago my pc arrived, the specs are as follows:

Asus rog crosshair viii hero WiFi

Asus tuf Rtx 3080

ryzen 9 5900x

corsair h150i elite capellix

corsair 400d airflow

commander pro

Corsair rm 850x gold power supply

And I bought three addition ml pro Corsair fans

Corsair mp600 m.2 pcie 4 2tb and 2tb 7200rpm seagate barracuda hard drive

Ram was Corsair rgb pro 3600mhz cas 16 ( I had it by 2 dual channel kits because I couldn’t find a quad channel pack).

I ordered this pc from a company called scan who built it and shipped it out to me last week. When I first got it I had no problems at all with the pc (except the hard drive wasn’t fully plugged in however I plugged it in a few days ago). However I have notice until the last 2 or 3 days that I get random drops in FPS I all my games. For example rocket league will play at 240 FPS perfectly and then drop to 18fps for about 0.5 seconds. This happens quite frequently in all my games and is becoming an issue. My temps are all fine with the gpu staying between 55-64 degrees in games and the cpu around 60-65 degrees (Celsius that is). There doesn’t seem to be a bottleneck as for rocket league the cpu barely goes past 10% usage and the house stays around 60%. My internet isn’t the problem as it is very stable and I have tested the connection multiple times. I have tried deleting msi afterburner as people suggested that could be a problem (no change). I have also tried lots of things in windows such as enabling and disabling things like game mode, gpu acceleration, background apps and I have also changed things in the midis control panel such as use 3D application settings. My windows is up to date and so is my graphics drivers. I use an Alienware AW2721D monitor, however I don’t believe this is an issue as I had no problems with this monitor with my gtx 1080 on my older pc.I honestly don’t know what the issue could be, loading times are perfect and everything seems to be running perfectly but the random FPS drops keep happening. Also just to confirm my FPS drops for only about 0.5 seconds then goes back to normal, my frames aren’t constantly low. They are also quite frequent and make games very hard to enjoy. If anyone has any suggestions on how to fix this all suggestions will be taken on board. Thanks again.
