[Muhammed]

Anyone knows how can solve that problem ???

What videocard do you have?
What OS do you have?
Which driver version did you install?

[Muhammed]

windows 10
GT 525m (old driver allows to launch ue4 games but new one doesn't)
391.35

[Insomnia]

Use the old Driver until the fix it? Probably the best idea

[Muhammed]

cant play any games
old driver doesnt support dx10 11 12

[Cathulhu]

If the old driver doesn't support it, then how was it able to run UE4 games?

[Muhammed]

look old drivers support ue4 games but %50 of my games are using ue4 %50 of my games using dx 10/11/12
with old one: ı can play just ue4 ones with bad optimization (cuz of old driver)
with new one: ı can't play ue4 games

[Cathulhu]

The bad performance has nothing to do with optimization.
It's your very old and weak mobile videocard.
Even today's integrated videochips are faster:

I know my graphic card is old but ı am tryin to tell
if ı use old one ı can't play dx 10/11/12 games
if ı use new one ı can't play unreal engine 4 games
and ı know cause of that is driver

[wuddih]

ddu the current driver. install it again, test again
if fail, ddu it again and install older driver version, test again
repeat until acceptable result.

500 series is out of service, the "newest" driver is a year old.

[Muhammed]

y they re ı know ı did it ı reinstalled my driver again and again and again ı tried to install every versions of drivers one by one (started from 391.35) ı couldn't find the right one
but when ı installed dell gt525m driver setup it installed a version in 200s but that version of driver doesn't support dx10/11/12 and decrease fps on games

[Cathulhu]

If it wouldn't support it, the game would crash on start. The fact that the game runs, shows that the driver supports it. The low FPS is caused by your really, really, really bad videocard.
Which was never designed for gaming in the first place.
