No my friend - it is not normal for the engine to frame drop from 60 to 10-20. This is a lag spike.
Not to mention when you encounter it once, reload a save, recreate it second time - its not happening. im talking about the sorce blast from our old lady wendy =)
It would be normal if this was a regular frame drop, going smoothly from 60 to 50-45, but not when it creates a spike that freezes your screen for a second.
And the sound issue - it is an issue, you confirmed it yourself [you followed my instruction and you admit that sound hang was there, frame drop also]. Its not specific to any rig, its not on a user end, its game engine global issue that need to be looked into - thats all.
I think you misunderstood me - im not ranting about the game, i love it as much as i loved the first one. Otherwise i would not back it up on KS back in the day and i wouldnt for sure buy it.
Im just reporting kinda serious issue - that for me creates an unplayable scenarios, breaks my enjoyment from the gameplay and therfore - makes the game unplayable durning first 30+ min of gameplay [usually after 30-40min of gameplay the issue occur less often - i asume its due to the fact the engine "reloaded" most of the problematic assets that creates those sound hangs and frame drops]
P.S.
And no - im not expecting larian to magically "pump my pc", im perfectly aware of the fact my rig will encounter some framerate drops from 60 to 40 in intense combat scenarios, thats ok, i dont mind it at all. Im just not ok with the anooying lag spikes and choppy sound =)
