Fallout 4 won’t play on your PC? It may be that it is not compatible with your system or it is not optimized for your graphics card or installed mods. There are several reasons why this could happen and we’ll cover each of them here. If the first one is the case then you can try running the game in compatibility mode. You may also need to uninstall any installed mods. However if this is the case you should follow the next few tips.
Fallout 4 won’t start
If you are having Fallout 4 you’ve probably encountered the error: Fallout 4 won’t start. This error is caused by one of many different things. One of the most common causes is the game’s files being corrupted or missing. To fix the issue you should check the integrity of the game files. Additionally you may need to update your system drive permissions which means it needs to be set to read and write.
Another cause of the Fallout 4 won’t start error is the display driver. If it is not up to date you may need to manually update your display drivers. If you cannot access this function visit the Device Manager. This may fix the problem. To get your game running again follow the steps below. If the problem persists you can contact the antivirus vendor. The last possible cause is excessive modding. Excessive modding will cause several problems as it can drastically change how the game operates. Therefore before you try to play Fallout 4 make sure to disable all your mods and enable them one by one. If you find that the mod is the cause delete it immediately.
It’s incompatible with your system
If you’ve recently tried to play Fallout 4 but have been unable to because of the game’s incompatibility with your system here are some helpful tips. First you’ll need a copy of Notepad which Microsoft recommends. If the file is long press CTRL + F and use the Find option to look for the code iNumHWThreads=2. This should fix the error and let you play Fallout 4 again.
You’ve probably noticed that the game won’t work on your system if it isn’t running on a 64-bit operating system. This is a known issue and it’s worth looking into. Fallout 4 needs to run on a 64-bit operating system. You can’t play it on a 32-bit system and it isn’t possible to upgrade to a 64-bit version if your PC doesn’t have a 64-bit processor. If your system is 64-bit you need to install the appropriate drivers. If you don’t have any of these installed you should download them from the official website of Bethesda.
It’s not optimized for your graphics card
You might have noticed that Fallout 4 doesn’t run very well on your graphics card. You probably have tried lowering the resolution or changing the settings but nothing seemed to work. This problem is a result of the game’s inability to run on your graphics card’s optimal settings. To fix this you can try forcing VSYNC or switching to W7 compatibility mode.
If you want to play the game at its highest fluidity you’ll need at least a GTX 960 or an R9 380. GTX 950 and deprecated R9 270X cards can only push 1080/ultra to a moderate degree. With some tweaking a GTX 960 can push the game at a comfortable 50FPS. An R9 285 can handle 54FPS on average but will occasionally tank to as low as 30% of the frametime.
It’s not optimized for your installed mods
If you experience the same issue when trying to play Fallout 4 there are several possible causes. Some of these problems can be traced to the modified.INI file. To fix this issue simply disable all of your mods and re-enable them one by one. Alternatively you can simply delete the mod that is causing this problem and try to launch Fallout 4 again. If the problem persists you should check the game files in your Steam folder CommonRedist and vcredist2012 folders.
In addition the game’s graphics and performance are not optimal. Users who have been playing Fallout 4 for several months have reported performance loss and FPS drops forcing them to turn to the use of PC performance mods. Thankfully these modifications can help fix the game’s performance problems. But before you can install mods you need to make sure that your system supports them. If you are running Fallout 4 on a low-end PC you should consider installing an appropriate graphics and performance mod.
It’s not compatible with your graphics card
If you are experiencing this issue the main problem is likely your graphics card. It has too low of a VRAM or dedicated video memory to run modern games well. To avoid running into this problem you should aim for at least 2GB of VRAM. Ideally you should aim for at least 3GB which is the recommended amount for Fallout 4.
The first step to resolve this issue is to install the latest version of the display driver. Using Steam you can also install the latest update for the game. In the meantime try testing the game to see if the black screen has been fixed. If your performance is still poor you can try downloading Game Fire which is free and works well for boosting game performance. You should be able to find this in the Steam Library.
