I've noticed pretty major Frame time spikes resulting in stuttering (FPS is stable) on Kislev siege battle maps. Only seems to happen, strangely enough, when the units starts moving. Tends to get better actually the longer the battle goes on but it remains present throughout.
Seems to be happening to me the worst on Kislev maps and is slightly better on Empire maps. I haven't noticed it anywhere else. My framerate is otherwise excellent and the game runs smoothly.
Anyone else having this issue?
