Hi,

I've had this laptop for about a year, and I was using it no problem until recently. I was running games like Space Marine 2 and Cyberpunk 2077 fine, and was recently playing Hades 2. I'm not sure if this was the cause but I updated my BIOS using Lenovo Venture last week, as well as updated my NVIDIA driver through the NVIDIA program. Since then I was getting lag spikes / frame drops on Hades 2, which is ridiculous since that's such a light game. Tabbing out with the game on also caused my screen to spaz out, I'm not sure how to describe it but my desktop would be layered three times or have portions of my screen displaying TV static, then stabilize when I tab back into the game or close it properly.

Earlier this week I tried fiddling with Lenovo Vantage and disabled the GPU Overclock as well as switched the GPU working mode from Hybrid to dedicated, which seemed to help; the spazzing out stopped, and Hades 2 was playing stable again. I thought, problem solved.

I tried booting up Space Marine 2 and Cyberpunk 2077 earlier today however and performance has cratered. Without changing any of the game settings, it's stuttering so much that it's basically unplayable; just looking around is like a slideshow, and driving around is impossible.

I tried reverting the settings in Lenovo Venture, turning back on the hybrid GPU mode and overclock. The spazzing out didn't come back but the performance is still terrible. I've since also tried updating my processor driver but that didn't help either.

Unsure if this is relevant, but here's a picture of my computer's performance under task manager, I noticed that GPU was hovering at 20-30% and memory was very stable at 56%.
