[SOLVED] GTA 5 Textures Dissapearing And Fps dropping after 20+ minutes

[Giorgi13]

PC SPECS:
Core 2 Quad Q9400 @Stock (running 70-80c at full load while playing GTA V)
Gigabyte G41M-S2PT
6gb 1333mhz RAM
AMD Radeon HD7770 1GB GDDR5 @Stock (60-65c)
Seagate Barracuda 500GB 7200RPM
420W PSU

So i switched from nvidia gt 430 to hd7770 and got new hdd.
i installed windows 10 and all the other basic stuff and everything seemed normal.
at first gta v automatically set settings to low but it made me laugh cause low settings gave me 80-130 fps.
then i set it to high settings and i had 40-50ish fps (not all things high only shadres textures and shadows) also resolution is 1280x1024.
Textures dissapear very often and after 20 minutes of gameplay,but temps are same... i get fps drops every 10-13 seconds.
please help !

Well my guess would be that you don't have nearly enough VRAM to run that game on high. The game cant load textures if it has nowhere to put them. I would try normal settings and see if the issue still occurs.

i am more concerned about the fps drops. the CPU isn't getting throttled and everything is fine. FPS drops were occurring when i had 4gb gt430 too. i dont get why it drops after 20 mins.

so recently my pc has Kernel Power crashes.
I am using molex to 6 pin connector which is bad but i don't have any other options yet (i'll buy new psu as soon as possible)
and i think i might be able to fix it this way:
the sata connector which is on same rail as molex connectors to 6 pin.
i connected sata with second cable(rail idk what is it called) which is connected to my 80nm fan.
i hope i won't have any issues and crashes anymore.
also if you are experiencing same problems stay here because i will update this post after full solution

I just found the Solution?(i think).
so after replacing hdd i didn't replace my really really old sata cable.
and you may now start laughing but i have proof.
after I got Disk boot failure message from my kernel power Crashes i and then after messing with hdd cables would turn on hdd again i've come to conclusion that The sata cable indeed is the fault here for my crashes.
i will start benchmarking today and if system crashes and all the other thins don't disappear i will shoot my head(jk) bye guys

as far as i can tell other people are running gta 5 with 1GB Vram on high with this gpu. you can look it up.
and i have also tried normal settings with same fps and results
