First, update all hardware drivers with digital signatures.

Optimization system (xp system is preferred)

In addition, your graphics card is relatively low-end.

Let's see what others say:

A low-end unique display, the performance is not as good as the previous generation GT240, and large games can run inefficiently.

Low-end entry-level gaming graphics card. The performance is similar to that of HD5570, but weaker than that of HD 6570 and HD 6670 (excluding those who castrate the memory with wide specifications and cheat money)

At the resolution of 1440×900, the game performance is average, and most games can be played, but the highest special effects cannot be guaranteed.

The reasonable price of this graphics card: 400 ~ 450 yuan. 1GB GD5 can sell for nearly 500.

The performance of GT440 is only 1/3 of GTX460. When playing games, the frame difference is more than double. If the frame number is only 20FPS when it is fully open (obviously it feels a little stuck at this time), then GTX460 should have 45-50FPS (very smooth).

There are 96 stream processors in GT440 and 336 in GTX460.
