Movement- feels very slow, if you have played/watched the streams- you can see that. The way they've structured the movement, adds some extra motion to the ragdolls (bodies). For example- you might have noticed both the feet moving separately, leaving the agent on the same place despite one feet moving to a wider stance.
Lighting- currently only with dust2, there are parts of the map which are extremely bright (A site for example). I know this is easily fixable, but from pictures of the other maps (lake, B site mirage), I don't really like it.
Nades- the worst part of it all. Where do I start- molotovs are an absolute joke. The colors of a molotov are brighter than the hair of a gen z addicted to a therapist. I hope that was an extended April fool joke and they change it in an update today. But the graphics of molotovs and he grenade seem like they belong in valarante
