There's something weird going on that's beyond just the PC that Odyssey is running on. People can run much more graphically demanding games at better framerates and smoothness (for example, MSFS 2020) on the same PC that bogs down to single-digit fps in Odyssey. Or, take this last update, where we have videos from Burr and his wife showing a serious performance nerf. I use them as an example because normally they are putting out some of the best video content for Odyssey, showing that on a normal day Odyssey performs fine for them.Following the many threads on performance, I am often asking myself what must be wrong with those PCs which are supposed to have more than enough resources to run ED:O in a decent manner. Therefore, I agree with Ratcatcher that it may have to do more with the configuration and updates of these underperforming machines than it has to do with ED:O itself.
And then there are people who are supposedly getting a locked 60 fps with no stutters on relatively older hardware. It doesn't make any sense to me, but I'm not convinced it's just the PC, otherwise all games would be equally affected, not just Odyssey. My PC runs all the games I have installed perfectly well (which includes some demanding modern titles), but I'm not going to roll the dice on Odyssey - its reputation is just too bad ATM.
