Скачать или смотреть Tips, pls? - Huge performance regression - Flight Simulator 2024 vs 2020

My new-ish ThinkPad P1 Gen 4 can handle Flight Simulator 2020 fine. It is playable with pretty graphics and mostly stable 30fps even in places like New York. However, Flight Simulator 2024 runs way worse. I suspect that VRAM usage is a little bit above 4GB, causing a huge performance hit vs when VRAM usage is always under 4GB. I spent a lot of time trying reducing texture-related settings to reduce VRAM load, but I am not sure if there's a special combo that I can use other than putting everything on super low.

Even at 1080p with DLSS (resulting in a 380p resolution), it does not run very well. FS2020 also loads way faster, even after caching everything.

I start flying above the Central Park (basic activity).
