Why did Assassin s Creed 4 lock 30 frames

Assassin 4 is designed like this,If your hardware configuration can't directly make the game stable at 60 frames,Even if you can run at 50 frames or 59 frames,Then the game is intelligently locked at 30 frames,And it won't let you run as many frames as you used to do to give you as many frames,This setting is really weird,The machine that could have run 40 frames or 50 frames was also made to run at 30 frames,It's annoying,The preliminary estimate is caused by the upgraded engine of the game,I observed the map environment design and GPU usage of this generation., It should be this problem.,But the official didn't give a statement.,The graphic design in the game is really complicated.,The grass is all roots.,More vegetation dynamics.,And you can't turn off this setting.,Especially in the wild, the frame rate is lower.,There's a stupid way to play if you want to increase the number of frames.,But the test has a little effect.,But the configuration of the scumbag is just that.,The method is like this.,First go to ** d3doverrider to install.,I won't be verbose about the specific use method.,It's very simple.,**Just look for the relevant instructions when you look for it., Then go to "My Documents" to find Assassin's creed iv black flag folder,Open it and find the configuration file of Assassin4,Double click to find [graphics dx11], change that dx11 to dx9,After changing it is [graphics dx9], there are three [graphics dx11] in this configuration file,All changed to dx9,After changing it, save and exit,Then run the game with the d3doverrider software., In this way, Assassin 4 can generally be increased by about 10 frames, but it is recommended to turn on VSync when running, although it has been emphasized that VSync should be turned off when using d3doverrider, but Assassin 4 is recommended to turn it on, otherwise some places may reach a high frame rate, but frame skipping is very powerful, I want to have a good experience of Assassin 4, so I still turn on VSYNC and use D3Doverrider.

If you turn VSync off, it won't lock.

In fact, it is not the 30 frames of the lock, it is the vertical synchronization, if the machine configuration is not good, it is the lock of 30 frames, and the good machine (more than 7000 assembled desktops) is the lock of 60 frames.

Turning off vertical balancing won't lock up to 30 frames. The more powerful machine can reach 60 fps on its own. However, if it is already locked to 30, it is recommended not to turn off the vertical balance, as there may be a feeling of separation.

The optimization is good, and the frame rate is relatively stable.

Much better than PSV's frame drop rate. But the resolution is hard to say.

1.First of all, check whether you prefer to use a discrete graphics card, if you start a game and the computer is set up to use an integrated graphics card, it will also be normal.

2.Second, make sure to check whether the graphics card driver needs to be upgraded and whether the driver is up to date when using a discrete graphics card.

3.If you need to upgrade, please upgrade the graphics card driver as required, and make a backup of the original driver before upgrading.

4.Before entering the game, make sure to close other programs and processes, as programs and processes outside the game will eat memory, graphics cards and other resources.

5.Make sure you have the latest version of DirectX installed on your computer

You see if it's open with integrated graphics.

System problem: This game is very smooth when replaced with win7.
