Took a while thanks to lack of availability and the time it took to dry my tears over the crazy prices, but, since you only live once, I bit the bulllet and condemned myself to poverty by buying a new GPU in the form of an AsRock Taichi RX 6800XT.
And as a result, I restarted Fallout 4 just to see if the game performed better than with my old Vega64.
And does it? Yes it does. Load times are significantly better and framerates are almost constantly at 60, or 59.9. I still have the game capped at 60fps and I also still game in 1080p. As such, the 6800XT is slightly overkill, I know. But, the GPU can manage Ultra settings where the Vega64 started trembling at the knees in Ultra.
But. Despite this beast of a GPU, FO4 still has serious framerate drops in the usual places like Boston Commons, along the Freedom Trail and Swann Lake. This to me shows that FO4 is in fact a miserable game, in that the optimisation regarding use of RAM is so poorly done that the GPU to run the game smoothly has yet to be invented.
But I'm okay with things as they stand. The water-and-bread I'll be consuming for the forseeable future will taste like a King's meal whenever I start FO4 and the game boots within 15 to 20 seconds and load screens take between 2 to 5 seconds, where before, when I still smoked, I had time to roll a cigarette when entering a building.
Anyone with a 3080 or 6800 who has some thoughts about FO4 now?
