GS/HW: Add new HPO - Align to Native With Texture Offset

[refractionpcsx2]

Description of Changes

New Half Pixel Offset option, based on Align Native but with texture adjustment and removes a very annoying vertex offset.

Rationale behind Changes

The vertex offset was causing problems in the RT in RT branch due to things being drawn offset in to a target, but by default the option leaves the first pixel blank due to a forced offset, this gets around that but needs to adjust texture coordinates also.

Suggested Testing Steps

Test games with the new option under the HPO upscaling fixes.

Known to be better for Ace Combat games, Catwoman, Madagascar and potentially others with borders. GOW also looks better on the RT in RT branch, as well as being required for FF7 DoC and Project Snowblind to avoid bad textures.

Align to Native

Align to Native Texture Offset

ATN Texture Offset is less blurry

Uhm..? I'd be curious to know where in ace combat this would be better, because in AC4 it seems worse.
Original
Align to Native
Align to Native - Texture
(this was with native scaling set on "aggressive".. without it, there is actually even an odd vertical line on the right edge)

idk how you got those results, but:

Original:

ATN (but keep in mind in another seen this absolutely breaks the clouds):

ATN Texture (which doesn't break the clouds):

That's why I think it's better for Ace Combat.

[mirh]

With original I meant software (you can see how much more it's lower res).
And I couldn't avoid to notice how normal ATN is pretty much (and finally!) its direct equivalent - just HD.

Then yeah, I saw just now that while actually flying ATNT fixes the sky.

[mirh]

Not bad at all now.
Then of course you do you (and I can guess that "texture offset" means that you should necessarily expect a bit of a constant shift in the position of stuff), but if I had to raise an objection the blur effect is still kinda screwed. Most notably it's no longer centred around the front landing gear (you can only see it, much stronger, on the right) and that metal thingy on the superstructure on the left with the ISAF logo has such a trail..

Pretty interesting! Will be testing this on my games and see how much this helps 👀

[pgert]

In "pcsx2/ImGui/FullscreenUI.cpp" it's still "Align To Native" & "Align to Native - With Texture Offset".
Any comment?

Might be worth checking SOTN with this, I had been testing with Native Scaling set to Normal and the water doesn't add the extra white lines while underwater.

If you have any other GSDumps for SOTC that might show weird upscaling issues, it might be worth checking on those too.

In "pcsx2/ImGui/FullscreenUI.cpp" it's still "Align To Native" & "Align to Native - With Texture Offset". Any comment?

No it isn't.

Edit: No you're right, sorry, I missed that.

[refractionpcsx2]

Thanks @AmyRoxwell ! Yeah I also noticed SOTC looks better with the new option, it gets rid of some side glow and stops some weird distance glitching that currently happens on master too.

Tested Armored Core Nexus (SLPS-25338 / SLPS-25339). The new option seems closer to Software compared to master (HPO Normal).
