NVIDIA's New DLSS 5 Graphics Feature Slows Games Down

NVIDIA's new DLSS 5 graphics enhancement debuts in NBA 2K27. Testing on NVIDIA's top RTX 5090 card shows enabling it drops frame rate from 240 to 150 fps and raises power use from ~400W to 525W, for "subtle" visual gains. Earlier DLSS versions boosted performance; DLSS 5's AI step reduces it. Worth flagging: the trade-off is inverted until the technology improves.
