Playing GTA4 on win8.1 Unrecognized analysis and solution for dual graphics card

Windows 8.1 dual graphics card notebook is not recognized when running Grand Theft Auto 4, the available resources of the game screen settings are 59M or a few Ten trillion, so that players can't adjust the picture to set up happy play. There is no such problem on Win8, Win7. I wrote a brief analysis of the case and solutions, we can refer to

dual graphics patch

Nvidia/AMD official driver

methods/steps

player feedback, Windows 8.1 system playing GTA4 has a problem with graphics card recognition failure, personally think that Windows 8.1 and graphics driver compatibility Caused by poor, there is no such problem in Windows 8 and Windows 7

AMD graphics card: AMD graphics card does not exist in the dual graphics card recognition problem caused by Chinese, but still need to uninstall the Chinese patch before it can be normal Using a discrete graphics card, I personally tested successfully

Delete d3d9.dll, font.dat, font.ini, Ref1.dds, Ref2.dds, Ref3.dds and restore the american.gxt file in the game directory

Open AMD Graphics Card Properties - Power - Switchable Graphics Global Mode - Manual or Depending on Power Select Graphics Processor - Select High Performance GPU: http://www.jb51.net/os/Windows8/289846 .html

1. Make sure the notebook is plugged in with an external power supply and works fine

2.Control Panel-System and Security-Power Options-Check High Performance

Nvidia display : Due to the failure of the graphics card switching failure caused by the GTA4 N card itself (Win7/Win8/Win8.1 exists), please download the GTA4 dual graphics card notebook patch (for 1.04/1.07): http://pan. baidu.com/s/1dDjHG3Z and correctly installed

Exclude the graphics recognition factor caused by Chineseization, of course you will find that the number of resources detected by the game is still 59M or tens of megabytes

Best It is to uninstall the Chinese version of the patch to directly eliminate the problem of the identification of the graphics card caused by the Chinese patch, and eliminate the hidden factor

Note:

1. Make sure the notebook is plugged in with an external power supply and works normally

2. Control Panel - System and Security - Power Options - Check High Performance

Select Preferred Graphics Processor for Program: Open Nvidia Control Center - Manage 3D Settings - Select Preferred Graphics for Programs - High-performance Nvidia processor - application

Directly force the discrete graphics card to work for rendering

Then create a new txt text file in the game directory, the file name is commandline

Save as follows:

-norestrictions

-availablevidmem 15

-percentvidmem 100%

Note: 15 This number changes according to the number of resources detected by the game. For example, the number of resources in the game screen setting is 59M, then the result of multiplying the number by 59 is less than 3000, in case 3G memory resolution adjustment limit problem

This method is to force the independent graphics card to work globally, borrow memory transfer memory to improve the amount of resources available to the game, and this method is to be discussed as follows. I have not tested, GTA4 bar friends by monitoring the temperature when running the game is considered to be state one, but the case is not convincing, but also hope that everyone feedback

state one: set the global independence and independence The graphics card is working, but the game can't recognize the memory of the discrete graphics card, so the amount of game resources is increased by the memory transfer memory

state 2: the core graphics card is working, the amount of game resources is provided through the memory transfer memory, I5/I7 board The performance of the nuclear display has reached the level of entry-level independence. After borrowing memory for video memory, it can run the game smoothly.

Notes

Ensure that the notebook is plugged in with external power and works. Normal, update the normal working graphics driver

Control Panel - System and Security - Power Options - check high performance

The above is to play GTA4 on win8.1 Unrecognized dual graphics analysis and Solution, I hope to help everyone!
