My NVIDIA developer journey - optimizing graphics card performance

When we buy anything, it is decided by more needs , Buying a computer is also , Sometimes it's for office , Just buy a light book ; Some are for playing games , Just buy a game book . Different needs will lead to different hardware that we buy computers , The most important thing to play games is the graphics card , Professional users may have paid more attention to CPU. We often use GPU, That is, the graphics card comes and goes , You'll find the use of CPU A model that will run for more than ten hours ,GPU It will be finished in half an hour , But there are still some people who want to be faster . Of course , Whether you are a game or a training model , There are very high requirements for the performance of graphics cards , So how to optimize NVIDIA The performance of the graphics card ？
Now let's take a look at how to optimize the performance of the graphics card ？

Right click on the desktop , Click on NVIDIA Enter the setting interface

adopt 《 Adjust image settings through preview 》 choice “ Use advanced 3D Images ” Set up 【 The default is from 3D The reference program determines （L）】

adopt 《 management 3D Set up 》 You will find that there is " Global settings " and " Program settings " Two
among Global settings apply to all games and programs
Program setting is to apply this setting in a customized single program

amount to ： Global settings are global variables in programming , Can be used
Program settings are local variables in programming , Only inside can be used

OpenGL Rendering GPU Choose your computer's graphics card 【 Here I am 3060】

Turn off vertical sync , The default is to use 3D Program settings
This option can eliminate the image “ Traverse ”, But the hardware requirements are very high , General advice “ force close ”

Maximum rendering ： Render the back picture in advance , The experience is very good , But it consumes a lot of performance . Equivalent to vertical synchronization , Prevent the picture from tearing . But if you want to eat chicken, it is generally not recommended to open .
Opening conditions ： If the picture is not smooth enough , Or occasionally get stuck . You can increase this number . Then enter the game , Caton's problem will be significantly improved , The picture will be much smoother . Maximum number of pre rendered frames , Is to make CPU Share it GPU The job of , Help it preprocess some frames in advance , This can reduce GPU The processing time of .
Suggested choice 1 , That is, don't render the following . The following virtual reality pre rendering frames are the same , The suggestion is 1
Finally, you need to click application to take effect .

It's almost here , There is not much loss of image quality , But the frame rate has increased . Feel more stable , Smoother .

Finally, three more ways to improve the performance of the graphics card ：

Method 1 ： Physical acceleration , Also known as PhysX Speed up settings
Physical acceleration is NVIDIA A technology that uses graphics cards to accelerate system performance .NVIDIA Physical acceleration of , I've tried , Turning on physical acceleration is indeed not a little better than before .
Open method ： Right click the desktop and click NVIDIA Enter the setting interface , In the graphics card control panel, there is a special door Of “ Set up PhysX To configure ” Options , The default is auto select , Choose your own graphics card , Force the system to use the graphics card for physical acceleration in the game （PhysX）.

Method 2 ： Update driver
Drivers for graphics cards that have just come into the market are generally not optimal , Generally, it will be gradually improved , Therefore, updating the graphics card driver will generally improve the system performance . There are always some problems in general installation , Sometimes uninstallation is not enough , At this time, it is usually a registry problem , It is recommended to uninstall the old graphics card driver and use the system cleaning tool to clean up the garbage and registry , Tinder is recommended here , Clean and free .

Method 3 ： The graphics card CUDA Speed up
NVIDIA The parallel computing architecture developed by the company CUDA technology , utilize GPU The ability of parallel processing , Greatly improve the scientific computing performance of the system . The stronger the performance of the graphics card ,CUDA The better the acceleration .CUDA technology , Now it is widely used in all aspects . And the most common application is video transcoding . at present , Most video transcoding software supports CUDA To accelerate the technology ,MediaCoder Is one of them .MediaCoder open CUDA Transcoding is very simple , Just click the encoder in the video column GPU, The software will automatically detect the acceleration of the graphics card .
