Heavy Underutilization on GTA V and low FPS

[DOGEY]

Hello, LTT forum community. 

After returning to GTA V, I get very heavy underutilization on both online and story mode, acheiving only 50 fps in apartment/home, but during 2018 I was playing GTA V on very high settings almost all max on 60 fps+, except for textures and MSAA with these specs:

Windows 10 Pro,
GTX 1050 2G
i5-8400 @ 2.8ghz, 4.0/4.2 boost all 6 cores*
8 GB RAM running at 2133 mhz
450W bronze/silver psu (i think it scored around mid tier on the tier list, idk the brand tho)
MB - Asrock Z370 Pro4

I've tried max settings with advanced graphics disabled and enabled, low settings, all 3 screen modes, vsync on and off, comandline.txt "Optimization" and have checked or noticed other things too:

My GPU Fan speed can't get recognized by any kind of software in RPM, but hwinfo64 sees it running at around ~50%, with temps being around 70, throttling only 20-30 mhz. I think that if I increase the speed in Afterburner, the fan might break, due to the fact that actually it started making noises during the winter that stopped after 5-10 mins, but eventually it they went away completely and the fan is working perfectly fine besides that now.
I was running an OC of +150 mhz core and +350-500 (i don't remember exactly) on mem, power limit on 100%, gpu fan speed on 80% limit, but i stopped using all of this, because I wanted to preserve the life of my GPU a bit more, since it looks like I am not gonna be buying a new GPU for long, just like many of us. Temps never went above 80C with it though. I think the oc gave a 5-6 fps increase in nearly all games i played, but on GTA V i don't know if it'll give me 60 at all.
Hwinfo showed that there was a performance limit on power, utilization and reliability voltage.
I've suspected it might be ram, but I have a page file of 2x my ram amount (16 gb) and the game uses about 3-5GB max real ram, depending on the size of it, currently using 3GB only. That shouldn't be it, I think, since the problem most likely is that the utilization is abysmal. CPU is at 50-60%, and GPU is at 60-70%, no matter the actual settings. Core 2 is at 70-80%, Core 5 50% and everything else 20-40%. If I could actually force the game to use max available resources, I can get nearly double framerate theoretically. (or at least +20-30 fps.)
That being said, more demanding games that can run, like Doom 2016 do it at a mix of medium to high settings (incl. a small amount of low), averaging around 60-100 fps, maxing everything.

The last things are the following: 
One time when i went into the game with my usual settings, I was averaging 65-80 fps, but after a quick minute it went down to 50, as if a switch had flipped.
I haven't updated my BIOS since I got my PC, at around March of 2018. The version isn't "Asrock v.XX" or whatever but is actually American Megatrends, Inc. P1.50, supposedly flashed in Novermber of 2017 by manufacturer probably.
I have speedstep, turbo boost and XMP enabled with everything set up.

If anyone has any idea what can help, please tell me.

Here is my ram usage during the bench.

It is well over 8gbs at 1080p and 1440p.

that was hundreds of windows , steam , driver , and games updates ago

consistency over a 3 years period with absolutely no regard into the software being used will yield inconsistent results. You cannot expect a machine to be consistent if nothing about it is consistent.

I guess you're right, but I didn't expect to lose so much fps just through updates and etc. If it's only that, i'm gonna get over it and just try and play at 50 fps avg. and not complain. In the end i'm looking for a solution, but there might not be one, that can specifically be done through settings and software exactly.

Hmm, strange. I wonder if there will be a change in performance if i decrease the page file size by just a little and try using more real ram. Maybe upgrading to 16 is the key. Thought about it for a bit.

Ram is cheap right now so it is a good time to upgrade.

 

Some of the ram I use is from my 2016 i7 6700k build so it can last a long time.

Thanks for the suggestion, I guess it's gonna be the first thing im gonna upgrade soon... If I try for a GPU I'm gonna end up starving for a month lol

I think I have the same problem

Several months ago I was playing GTA V at 60 FPS without any problems but now it falls about 40 or even 26! I haven't touched this game since last time (which there wasn't any problems that time).

CPU: i7700K

GPU: GTX1070 (MSI)

RAM: 16GB

game is on HDD

Windows 10 enterprise 

I've posted more explanation in another topic:
