Pogledaj cijelu verziju : Problem sa slikom u igrama
U zadnje vrijeme počele su mi se događati dosta čudne smetnje u igrama koje su mi prije radile bez problema.
uglavnom, da sad ne opisivam, evo screen iz mount & bladea:
http://www.imagesforme.com/out.php/i514788_mb.JPG
problem su ove kockice i razne amomalije (ne znam kako bih to nazvao) na ekranu i javlja se u svim igrama koje imam instalirane.
instalirao sam i najnovije ATI drivere... ništa
kad izađem iz igre, te smetnje nekad ostanu neko vrijeme i na desktopu.
ako itko zna o čemu bi se moglo raditi, bio bih zahvalan.
EDIT: zbog laga mi je napravilo 2 teme :(
Nisam čitao post, jer čim vidim sliku, znam da je riječ o artifaktima. Grafička ti, ili nije dobro OverClockirana, ili joj rikava memorija/GPU.

odi u catalyst i smanji si frekvenciju grafe...to bi trebalo rjesit tvoj problem
To ne riješava problem pregrijavanja, niti crkavanja grafičke. Eventualno će trajati par dana duže, nego što bi onako crkla.
Ako smanjim frekvenciju, dobivam slabije performanse što mi nije u interesu.
Dovesti ću jednog lika što se kuži u to kod sebe pa će on još provjeriti, ali već gledam koju ću novu kupiti.
Probaj ocistiti graficku od prašine.
Ako ni to ne upali, onda moras nabaviti novu.
očistio sam prašinu s ralica ventilatora ali nema promjene. ostatak grafičke izgleda čisto.
Onda odmah pitanje, koliko para planiraš baciti na novu VGA?
oko tisuću kuna. Možda i više ako bude isplativo.
Uglavnom sad za tisuću kuna dobijem bolju od te koja je koštala tri tisuće prije godinu i po kad sam ju kupio (ATI HD 2900 XT).
Nešto me privlači GeForce GTS 250 1 GB.
http://www.protis.hr/artiklprozor.aspx?ID=20932S?
kolika je razlika u performansama između tog modela i modela sa 512 MB?
kakvo je tvoje mišljenje o toj kartici?
i, ako imaš još neke alternative, slobodno reci :D
Daj mi tehničke podatke te tvoje, pa ću znati razliku. :D
