Beta (City of) Los Injurus 2023-12-20

You have a 4gb GPU connected by 4x PCI-E 3.0, since your G-series CPU does not support PCI-E 4.0 unlike main-stream chiplet-based Ryzen processors of 3000-series and higher. G-series (and their F-series counterparts) are mostly OEM chips and they have half the cache, don't support PCI-E 4.0. To support PCI-E 4.0, you need a Ryzen 3500 or higher, or 5500 or higher, but you'll know if you look up the technical documents (and you can tell by how much L3 cache it has per core).
If you go over your video memory allotment of 4gb, the system is hamstrung on the pci-e 3.0 x4 width bandwidth of those RX 6400 cards trying to access system memory. You have to use the lower texture settings for now, if you want good textures then buy a fairly good GPU or any that uses the full x16 slot bandwidth, and make sure it has enough memory to support the texture setting.
My recommendations on textures are just a suggestion, and I don't edit them or test them every last time I update Los Injurus as I don't always have time (when I could spend that time fixing my house or actually making progress on editing things in Los Injurus). What may work fine on Nvidia may not work on AMD or vice-versa, depending on hardware configurations or other things out of my control.
Sorry your not happy, but I ran this on Low on a Radeon 7850 2GB card I bought back in 2013, and it ran just fine with some room to spare - even though the 'old concrete' highway textures looked really blurry.

Building a capable gaming PC from used parts (often readily available locally or definitely on online websites) does not cost as much as most people think. In-fact, you can amass an amazingly capable computer for under 300~500$ with used parts today.
After the holidays, I am sure there will be a lot of last-year's hardware available cheap on the used market (there almost always is).
So keep your eyes peeled while being mindful of scams if using sites like Craig's list or Facebook - pay in person and try to verify it works first. If you think I didn't buy a few used parts to put in here on this development PC, you'd be mistaken. Power supply units and hard drives / SSD's you SHOULD buy new if you can; the rest of it, get whatever is decently a good deal and you know works.
There's plenty of info on youtube available to everyone who wants to learn how to do anything described above, from buying to building, to configuring the BIOS (if needed) and making it do what you want it to do.
--Good luck!

There's an odd bug with the 0.30 update. I am still looking into it and hope to have a fix soon for it. No one wants half a map!
It *IS* working as described on the tin (normally) on my end, however with this current version. A few other folks have this same bug so I am trying to get to the bottom of it before next week's public update.

I run this through 'the cleaner' to remove unused assets before uploading any public-facing versions of this map. I could cut-down on some things else-wise but this would ruin both the variety and hand-drawn nature (and immersion) in the map. In real life, each road is a little different, and this map should resemble that.

I am trying to keep requirements for the final version in-line with what is required now. Of-course they may go up a little, but it's slow and gradual over time. There won't be a sudden massive change in requirements, but like anything with assets being added over time, the requirements will slowly creep higher.
