Resolution and Upscaler

Ultraforge 1.0 Beta Testing (Works without problems on my workstation)
Windows 11 Pro - 128GB RAM - Gigabyte GeForce RTX 3070 Ti-OC-Vision 8GB
Checkpoints: SD 1.5 *.safetensor (https://civitai.com/models)

Hello,

As recommended and with the initial resolution of SD 1.5 (512x512), rendering is very fast.
When I try in 768 or 1024 (Initial Setup) the rendering is very slow.
(Image width and height: Both must be a multiple of 32).

I tried to stay at 512 as initial, then enlarge with a function. But it's still long.

Will you integrate an initial upscaler function/module ? (like ESRGAN)

I don't have any experience in upscaling AI images, (compared to a standard image) but this article gives us an idea of the process:
- Why can’t we use a traditional upscaler ?

Thank you for your information
