When i aim with my plane Yak-9k objects and trees get strangely deformed and become gigantic, completely obstructing my view and causing lag in the game, happened for the first time on the map “El alamein”. I dont think that the problem was my plane, because its my first match after the last update.
Try deleting the folders “Patch”, “compiledShaders” and “Cache” from warthunder installation.
When done, under Steam “Verify Game Files” and wait for it to finish.
There’s been another player reporting graphical glitches that were resolved by doing the verification dance.
