My physical copy of Dead Cells should arrive tomorrow or on Wednesday. The developers have admitted that the game drops into the 40-50 fps range, but not how frequently it happens; they've also promised a patch in case there are many complaints, but said patch wouldn't arrive before November. Players have claimed that the game can drop into the 20-30 fps range, but exaggeration is common on the internet. Of course framerate drops correlate with which weapons are used, because some of them have more demanding special effects. Locations also play a part.
I'll be able to tell you about my personal experience in a few days. I expect the game to run fine most of the time and most framerate drops to be bearable, i.e. without a significant negative effect on controls and gameplay.
That's great, Rol. Thank you very much for the post. Look forward to your impressions.
