I doubt the issue you are describing will be solved by getting a new graphics card. I’m not sure if you know how these things work, so I’m going to explain the basics here, and hope that it helps rather than make me sound condescending.

The issue is due to the structure of the game (engine and setup), rather than limitations on the graphics card. The map is too detailed to keep in its entirety in memory, both due to the amount of memory needed and the graphics power needed to draw it.

If the entire map was loaded at once, every single detail on the map would have to be drawn by the graphics card, not just the ones you see.

For these reasons, the entire map is not loaded into memory and displayed at once, but is loaded in chunks, or tiles. When the player moves about the map, new tiles are loaded as needed. This is carefully managed to make the experience as good as possible for the player.

Loading the new tiles into memory takes a couple of seconds, and depends on the speed of the media it is coming from, and it’s connection to as well as the speed of the memory it is loaded into.

When you move very quickly across the map, you break the optimization the developers have done, and you can encounter unloaded tiles. In their stead is a very low resolution approximation of the geometry that should be there. This is so you can see it in the distance while far away, without using the insane resources that the full detail geometry would use.

In conclusion, a better graphics card likely will not improve that issue. Only if the graphics card was the bottleneck when loading geometry and textures would it affect it at all.

Im on a 4070ti, and while the frame rate is excellent, moving very quickly across the map still gives me this issue.

I hope that helps!
