I am sadly puzzled by posts like these because they reflect some sort of weird dichotomy regarding EDO. I have a very average system, a GTX 1660 with but 6Gb VRAM paired with an Intel i5 3.50 GHz, 16Gb RAM, and U11 has been a very pleasant success for me, with good to excellent frame rates, a very noticeable reduction in graphics artifacts and LOD cludginess, and consistently smooth performance in settlements, my carrier, and now, on planet surfaces out in the black. For the first time since before FCs dropped I'm playing Elite without having to notice and excuse how poorly it performs. I truly wish I could pass on tips to achieving this Nirvana, but I really have no clue as to why it should be so when Cmdrs with much beefier systems are still lamenting. I certainly do not claim any special knowledge or skill in rig-tuning, it just happened. The only change I made lately has been to tweak a few graphics Quality settings according to the recommendation I discovered in GFE for ED optimization, but Odyssey was performing very well for me before that. Is it perfect? Nope, there are a few annoyances concerning AA and slow initial LOD transitions when I log in, but these are easy to ignore, especially given the much greater improvements.
Had I some way to share my good fortune (tbh I can't chalk it up to anything else), I would do so in a NY microsecond.
I think the best way to reply is with the fact that im surely running elite under the
actual minimum system requirements. Its just an unfortunate circumstance really. My machines are at the recommended spec on the steam page, but all the people who make it through have double or much more the gpu power that im running with on pc. That's the dichotomy.
There's a reasonable argument that realistically i shouldn't be trying it. Sure im able to play horizons on ultra etc, and if you don't want to consider the minimum requirements a material lie, they're were at best a far future target, which since they've given up on consoles, they're certainly not going to hit on pc either.
Another interesting factor could be that the increased system requirements are not that strictly there to be used for the highest graphical fidelity, but more to absorb bugs and lack of optimisation in the renderer. These types of gpu cost you can't really or easily just turn off in one of the settings (and i've had a blast of a time trying, love tweaking settings). As you're playing when these hit, they also don't leave an impression of "whoa that scene was crazy i was a bit to ambitious with high/ultra settings" its more like "i was doing nothing and the framerate halved, colourful insults and erosion of goodwill".
Some data for you though, yeah i get a robust 60 fps in space, and even in fleet carrier interiors assuming a jump has not been queued. Try that on your 1660, its not that fine

Its only when some sort of odysee structure intended to be used on foot comes into the scene the entire experience of the game just starts to erode. Try playing odysee content

Yes sure horizons content probably works fine now.
pps. my first and best love for graphics was that so amazing for the time voodoo2 sli setup i had. I'm used to 20fps really. But i do expect bleeding edge world changing marvels for it, as it was back the last time i had to play like that. Early ps4 era graphics for 20fps is rejected, sorry. Minimum i expect for that is 45 or bust.
