FoveatedDLSS5 mod boosts Neural Rendering on ultrawide monitors

Modder maximedgoulet released FoveatedDLSS5, a ReShade add-on that lowers neural rendering resolution toward screen edges, mimicking VR foveation. The Witcher 3 on an RTX 4090 at 7680x2160 rose from 49 to about 80 FPS, though the mod disables itself at 3440x1440.

• The Witcher 3 on RTX 4090 at 7680x2160: 49 to ~80 FPS, over 60% gain
• At 7680x2160 neural rendering processes about 71% of original pixels
• At 4K 93% of pixels remain; at 3440x1440 the mod turns off
• Only works when neural rendering runs after upscaling, not with Neural Upstream
