Decide to make this guide since there are so many people encounter this problem

I guess not everyone will go to discussion and find out the solution themselves

I am using Window 10, if you are using other platform please don't ask me how to do it

Only work with PC using NIVIDA graphic card

1. Right click on your desktop and click on "NIVDIA Control Panel"

2. Manage 3D Settings => Program Settings tab

3. In "1. Select a program to customise:" click "Add"

4. Navigate Death end re;Quest local game file, find "Application.exe" file
if you can't find it, you can go to your Library
right click Death end re;Quest, => Properties => LOCAL FILES => BROWSE LOCAL FILES...
The location should be like this:
C:\Program Files (x86)\Steam\steamapps\common\Death end reQuest\resoure\bin\Application.exe

5.In "2. Select the preferred graphics processor for this program:"
select "High-performance NVIDIA processor"

6. Start the game and play it

Before I used this method my FPS is 4-7 average, I can't ever play the game

I guess the reason behind this is Intel graphic card don't support this game,
The game does not change to use another graphic that support it

For what we are doing above is change the graphic card manually
Hope they fix this soon
