Strange graphics clipping glitch

[Vitoria90 10]

Hello. I recently got SC4 on GOG, and I immediately looked for guides on how to make it run properly on Windows 10.

I ended up on this topic, where I downloaded all of those mods and set them up (minus reshade, as my monitors are not HDR)

Yet on my game, there's some weird issue of transparency or clipping where certain layers of visuals get cut off when I move my camera (notice the half cut off industrial buildings on the bottom left of the first image). It also affects zoning overlays while I'm trying to place them, where they seem to clip through the terrain, but I didn't get a screenshot of it.

Specs:
SimCity 4 Deluxe Edition (GOG)
Win 10 Pro
AMD Ryzen 5 3600
16gb RAM
AMD Radeon RX 6600 XT (8gb)

Anyone know a fix to this problem? It's really disorienting, makes the game nearly unplayable.

This is a common problem with AMD GPUs. You should change some settings through AMD Adrenalin, but since AMD has changed the UI and settings significantly since the guide was written, you will need to run several tests to find the right settings.

Reshade applies filters to improve graphics quality, using so-called Fake HDR to achieve an HDR effect even on monitors without HDR support.

OK, I've had a look at those settings again, which I already had messed with following a guide. Apparently  the main issue was Tesselation Mode was set to AMD Optimized. I'm still getting a much lighter version of the glitch with the traffic, but at least the buildings and overlays now all render correctly.

The odd thing on that front is I have everything here off. Wish I could get rid of the issue completely. Thank you already for the help.

I don't know if it's possible, but try disabling Tesselation Mode for SC4.

If I set it to Override app settings then it lets me choose the tessellation level and in that I can pick 'Off', but it doesn't seem to solve the problem. Any other ideas?

Unfortunately, I don't have an AMD GPU, so it's difficult for me to help you. Try tweaking some settings and see what happens.  The fact that Tesselation Mode partially solves the problem also proves to change the settings of Dgvoodoo with DirectX 12 and 11.

I temporarily disabled DGVoodoo and tried this guide and it fixes the glitch, but the framerate becomes terrible

Try using this wrapper

Okay okay I found a fix: Set DGVoodoo to DirectX11 featureset.

Thank you for the help.
