How to fix too much lags in Shooter Demo by Epic on Unreal Engine 4.4.3

I remember Shooter Demo worked really very smooth on Unreal engine 4.2 but in The version Unreal Engine 4.4.3 there are so many lags especially while shooting. The fps of the games becomes too low so how can I fix it?

I haven’t looked at it yet, but are there any large loops in the blueprints? I remember in the BP tutorials that he had to edit the loop function with a ‘wait’ to keep large loops from locking up the system.

its mainly in c++ with pretty minimal blueprint use and ive tried all versions from 4.2 till now and it always runs very smooth…i havent tried with more than 4 bots though

You can already tweak the post process volume present in your level adjusting or removing effects.
In Quick settings you can also change some quality levels as your game will still look very good decreasing some of them, changing Shadows or Anti Aliasing from Epic to other values will increase a lot performance

I don’t think it is the problem of the effects.
