Wouldn't be so sure about that, lots of issues with TD2 are Ubisoft's fault. For me right now it at least works ok with DX11 but the game is often borked in DX12 and has been generally unstable since about 2 years ago, even with RDNA 2. Actually it had serious issues even on consoles, similar to on PC. Imo their engine is just too finnicky (TD1 was even more absurdly flarked) & requires a lot of on-going maintenance but in their infinite wisdom they've decided to axe all Massive staff support and instead pawn it off to a new support studio which ofc had no knowledge of engine/game but now has to untangle all the spaghetti that's Snowdrop. Predictably it's going not so well, and it's going to be a long while until they figure it out better.
