Seriously... i have been waiting for someone to do this mod, but I got tired of waiting. For a GTA Fan like me, I need this mod so I made it for myself and you guys. BTW i made this all from scratch and took me a lot of work! The original fonts was 512x512 dimensions. And i changed it to 2048x2048 dimensions. Perfect for 1080p monitors.
v1.0 Added HD font textures for GTA Vice City
v1.1 Might add grunge effect
v1.2 I'm not thinking this far into the future...
1. Some are not properly aligned because I kind of rushed it, next version will come soon.
If you want to vectorize them, I would recomend Inkscape. It's what I used to make the HD weapon icons for SA, it works wonders and it's easy to use.
And I can at least sympathize with the difficulty of making HD fonts for VC, since I attempted it once too. Needless to say, the result wasn't good enough to release.
The Rage Itallic font available on the net does not even match the one used by Rockstar, which resulted in messed up fonts on locations such as Starfish Island (same problem in your current fonts).
Zera: I tried my best to recreate it using just Adobe Photoshop CS6. It did however took hours to do and i have to find fonts to fit exactly since I don't have Adobe Illustrator. I wanted to vectorise it and then rasterise for perfect sharp quality but like i said, i have no Adobe Illustrator... Sorry about that. I'll try to align them properly.
Not a fan of these. It seems you didn't put that much effort into making sure the fonts matched the original exactly, which results in mispositioned letters on the screen. This appears to be a rushed job, no offence. And looking at the texture itself, you left the blurry original letters behind some of the high-res ones, which indicates a sloppy job on an editing program. There are many ways you can still improve this.
