Hearing even with day one patch these are problems people are facing:
Slow downs and lags when on hills, heavy populated areas, transitioning to towns, weather in affect, Let's Go feature, lots of Pokemon on the field.
That there are lots of stilted animations with background npcs, background animations and the like. I.E Sunflora running.
Character and Pokemon pop in glitches and lags.
Let's Go feature, Pokemon are still slow and will pop in and out if you command them faster than they can run.
I'm still unsure if these are problems because the game hasn't officially released yet, if its a patch problem, if its because they are emulating it on a rom.
But I keep looking at the last trailer we have and even though SWSH had texture problems it looked and played it was shown in the trailer. So I have to have faifth that the game on release will also run and look like it does in the gameplay part of the trailers.
