Once again us 5080 peasants gonna have to chose between nextgen lighting and 60fps at decent enough IQ( 4k dlssed perfomance is 1080p internal res).
Under those settings game drops into 50s easily on 5080 which means we will have to go with ultra perf 4k dlss aka internal res of 720p- 1/9th of 4k native pixels compared to 1/4th with dlss perf which siginficantly degrades IQ even more

5090 master race wont experience that problem at all, hell maybe they can even play game on 4k dlss balanced, if only i spent 4k usd on my gpu...
