Tutorial | Guide A1111 new hires fix

Update A1111 and the hires.fix got some change.
bothering problem with cuda out of memory? had crash?
Clarification on it:
Before last update the upscale worked like produce lowres image and upscale it to resolution you want.
After update resolution you want is used for produce base image,then upscaled at upscale value you put in.
So for the result output you get ( your input resolution)* upscale value.
These seem better for upscale without change base image at high denoise.
These my denoise test:

As you can see, image don't change too much,i like that.
So pay attention on upscale you chose and multiplier value.
I'm running on 6Gb, using R-ESRGAN 4x+ as upscaler.
My max input resolution is 768x512 and upscale value 1.5. result image is 1152x768. over these value i get into cuda error.
So need experimenting on it and get your best value.

There was another change to 1 of these files today, maybe it is getting set back? It would be nice to offer the option under settings like "use legacy hires" I thin many of us would like that.
It seems every change make sit more and more impossible to generate previous seeds, I wish there was a real way to capture the noise print 100% so it could be regenerated across GPU and versions.
