It looks like Warhammer : Vermintide 2 has been optimised for series S/X just downloading the update on my series S now. Supposed to be 60 FPS but unsure of anything else
Thank you; the additional pair of eyes you and others provide helps this thread out tremendously! It's great seeing devs throw in some unforeseen support, even if it is just simply doubling the frame rate.
Really surprised this hasn't made news but Crysis Remastered is getting a next gen specific update.
He mentions bringing back the 60FPS cap on next gen while leaving all modes locked to 30 on last gen. I assume we'll be getting the 4K/30 mode with an uncapped Framerate. Hope they touch on the ray tracing mode as well but I just want the regular mode to be 4K/60 tbh.
Ooohhh, nice! This is definitely worth keeping an eye out for.
