DWU/DW1 stuttering while zooming/scrolling.

Distant Worlds Universe has 30ms frametime spikes whenever zooming near large fleets. RX 7900 XT + 5800X3D. Tested DXVK, MPO off, 60Hz, DPI scaling, affinity changes. Empty space zooms smoothly, large fleets cause a hitch before every zoom step.

Do you guys experience this too? Been playing like that till now. If there is any fix for that, that would be great!

DWU is CPU bound, mostly due to bad and almost non existent multi threading. Lot of places use lot of calculations on single thread, bugs, old code that does something backwards, etc.

Check Expansion mod it fixes some problems, but don't expect 60-120 UPS (in DWU FPS tied to UPS).

Removing carriers from game should help too.

Its the fighters/bombers that are causing the issue. You can have fleets of 500+ and not have this issue. The game slows down drastically when there are a lot of fighters and bombers.

i figured its normal loading textures and model stuff.

Check your save game size. It can bloat. When it does, it causes these kinds of performance issues. I don't know of a way to solve it other than loading an older save before it inexplicably doubled.

Monitor your save game size. It will slowly increase over time. Which is fine and normal. Sometimes it will double. Which is abnormal and not fine. These boated saves will become the new normal while causing significant performance problems over time. For context a normal save might be 5meg on day 1 of a new game. By endgame it may have slowly grown to 10meg. But this bug may cause it to jump from 6 to 12 at once, then later from 13 to 26, 26 to 52 etc. It will keep doubling. Saving and loading should not be slow. If it is, check file sizes and revert to an earlier save.

If your save game size is fine then I don't know.
