I have been playing Insurgency sandstorm for a long time. I never had any issues with overall performance despite having a computer that can't handle it. After the most recent update, my game started crashing on startups, severe FPS drops, shader glitches and the worst; stuttering. I'm not gonna hesitate telling the truth here, I don't usually pay for gaming but I really love this game and I thought it would be really worth 30 Euros so I bought it. But it pains me to be not able to play it properly now.
Gameplay here, see how much worse it got. I have already mentioned all of my complaints sending crash reports. Yet no one ever did reply or anything I suppose the developers are too busy counting money.
their "hotfix" added more stuttering and done this to the game:
You can temporarily prevent stuttering by deleting insurgency and UE4 folders, reinstalling the game. It will not be fixed completely but it gets better.
