DirectX error
I'm very busy these days, but so far after looking up 20-ish posts on this problem, none of the suggested solutions didn't work. On the picture you can see that the error didn't mention the hardware as it is mentioned on other peoples case. I bought the game almost a year ago and it was running good up until around 20th October when launched the game after not playing it for a month. I can't play multiplayer nor singleplayer. For example, when joining a server, battlelog shows me that im joining the server, then the error pops up and after pressing ok the game disappears from taskbar. (*inhale*) I updated all drivers (ALL drivers), disabled origin in game, repaired game, reinstalled vcredist_x64 and x86 (Program Files (x86)\Origin Games\Battlefield 4\__Installer\vc\vc2012Update3\redist), changed language for non-unicode programs, uninstalled geforce experience, returned to older graphics card driver, ran dxsetup.exe (Program Files (x86)\Origin Games\Battlefield 4\__Installer\directx\redist). (*gasp*) The game is on my notebook laptop Asus n550jk with: Intel i5 4800H, nVidia GeForce GTX 850m 2GB VRAM, 4GB RAM LDDR3, 750 HDD 7200 rpm (or something close, can't remember), FHD IPS 60Hz monitor, Windows 10 Pro (upgraded in January from Windows 8.1 Pro and it worked on both systems up until above mentioned time). I'm a newbie to these forums so I don't want to offend (trigger) anyone, I didn't invest in this game to get these problems but to play the game. I know these problem had someone in this abyss of questions but I can't find the solution that works. Sorry to waste your time. Thank you in advance. Have a nice day!
First of all, I want to apologize for not replying sooner. I gave up on BF4 at that time and wasn't checking for emails that notify me on replies.
But recently I stumbled on a "BF4 funny moments" video on YT and I wanted to try to fix it again. Apparently my 4GB RAM stick at 800MHz and it can't be changed in BIOS. Found two videos from seven months ago (approximately when Win 10 anniversary update came and my error appeared) which told me to set "GstRender.FullscreenEnabled 1 ; GstRender.FullscreenMode 0 ; GstRender.OverallGraphicsQuality 0 or 1" in PROFSAVE_profile in "C:\Users\Me\Documents\Battlefield 4\settings". Surprise surprise it didn't work. Voodoo magic also doesn't help.
Finally my last resort that I avoided was to uninstall and download because 30GB will take me three days at max plus the possibility that the game still won't work. Apparently the game works after downloading the base game (dlc is still being downloaded at the time of writing this).
In conclusion you have to uninstall and download again to fix this kind of error.
