Not sure if this a bug or just needs adjusting.
I created a small target practise mission for the P51 using some civilian trucks (light blue colour trucks), for the test I have lables on at 10000m and off at 5000m so know where they are while futher out but have to search the closer I get too them.
The issue is when coming in at a dive angle to straff the tragets I notice that they are not in view and that they pop into view at about 200-300m and they also slightly shift/jump position as the LOD in the model changes.
This was not a issue in the A10 as we were using Mavs and locking up targets with the camera but for the P51 where we are in close to the traget they really need to be in the game world from 10000m or more so we can at least see targets on the ground a bit more clearly.
I need to go back to A10 and see if this issue was in that game as it just may be a DCS World bug.
