Fps drops during raid

I've seen similiar posts, but I have horrible fps drops during serp/aporia raid... I've tried a lot (lowering graphics, setting priority, closing everything else, and so on) is there really nothing else than upgrading hardware? I know my hardware is dated (ryzen 5 3400g, GTX 1650, 16gb DDR ram) but it works fine for everything else than raids (Pruinaum is fine too, tho?)

Thanks ahead of time
