1. The jam caused by insufficient memory is manifested in turning around at high speed.

Solution: After the game is set up, the game will tell you how much memory you will occupy under the current settings. The video memory occupancy value here is actually a super peak occupancy, which will only appear when all special effects and all materials are loaded.

Capture phenomenon 2: the capture phenomenon caused by the bug of vertical synchronization of the game itself is very similar to that caused by memory overflow, and it is almost indistinguishable. If you want to distinguish, you can only use the exclusion method. If the main monitoring software of N2O game is used to judge that there is no memory overflow, it can be judged as grabbing phenomenon 2 or grabbing phenomenon 3.

Solution: This is a bug of vertical synchronization of the game itself (which conflicts with the refresh rate, as mentioned by others in the post). If you use the default "on" vertical synchronization, the game is easy to get stuck. The solution is actually very simple. You can use another vertical synchronization mode of the game "half" to make the game start vertical synchronization under 30 frames, which is a perfect solution.
