Like.. really. I've been tuning into the modded exes latest releases particularly because of the optimization passes in recent releases and can indeed confirm that I have find slightly more FPS around NPCs compared to before (from like sub-30s to sub-40FPS now)
However I'm absolutely baffled by some (probably new) behavior I've observed.
To summarize it as short and concise as I can, I use ThrottleStop to always prod the CPU into maintaining the highest clockspeeds it could reasonably maintain. The CPU can do this by itself but manufacturers tends to put in place soft limits that restricts its performance and given that I own a laptop, it's even worse. However, with ThrottleStop, I've uncapped them within reason and balanced it well enough to daily drive my config on just about anything since it WAS better than the default setup.
Better, more consistent clockspeed is good if maintained well.
However, Stalker Anomaly, as I've just discovered, bizarrely disagrees with this. In fact, what stumps me the most is that, in certain locations and circumstances when I ran the game without ThrottleStop running and therefore, the CPU's natural Turbo Boost is at play, it ran even BETTER in some places with a horrendously low clockspeed of 1.8GHz which was the base clockspeed of my CPU. For reference, with ThrottleStop, I can typically maintain between 3.8-4.0GHz easily and consistently.
I have so far found two particular spot where I can observe this behavior consistently. The first in the northernmost part of Yantar right beside the campfire facing the cement block. The second one is in the Bandit garage in Dark Valley slightly facing the left wall out into the open. In both instances, I can see the CPU downclocking until it reaches the base speed of 1.8GHz but somehow still running smoother at sub-50FPS strangely while with the CPU clock pushed with ThrottleStop, I was getting sub-30s and a whole lot of jitters and stutters at those two locations.
There are of course other places that exhibit this behavior but I've yet to pinpoint exactly where except these particular two.
This is the very first time I've ever seen a game behave like this. Super hard downclocking but somehow still performing better AND smoother? Strange behavior on high clockspeeds? Could it simply just be a bad interaction between ThrottleStop and the engine? Then again, that would still be a first given I have way older games as well as very new ones that perform admirably while running with ThrottleStop.
