I recently reinstalled RTW on my PC and started a campaign, but the campaign map is lagging whenever I try to scroll around the map. Has anyone faced this bug before? I don't think this has anything to do with my PC or GPU since my rig can handle most games quite comfortably. Also, this lag happens only in the campaign map. I played a few custom battles and they are all doing very good, even at huge army scale. No lags in the battle map whatsoever. What could be causing this lag in the campaign map? Also its only when I scroll around the map that its lagging. Selecting units, ships, moving armies, characters around work fine without lags. Its just the scrolling that lags and the drop in fps is quite large, it goes down to nearly 10 or less sometimes. Is there a work around for this?

Does anyone else have this issue?

Btw, I have a i5 2500k processor @ 3.3 Ghz and ASUS GTX 550 Ti GPU. I don't think this has anything to do with system requirements, because there is no lag in battles even at huge unit scales.

P.S: Please don't tell me I have to have an older rig to run this game I sold off my old pc
