The quality is at the level of DLSS 1.0 !
I tested some custom resolutions and custom aspect ratios with the CRU Tool, which modify the nativ resolution of my TV to any resolution i need.
The DLDSR was able to run in 4:3 and much higher resolutions than 1440p or 1620p.
The result is, that even in 4:3 resolutions the performance is not good enough, and even in higher resolutions the image is not sharp enough !
G3D works, but it is not worth to use DLDSR.
DLDSR is not open source, so nobody can modify it for our needs. The vorpx FSR feature is great, but DLDSR is not worth it !
