Hi coonglinh,

Is the issue seen with this particular game only? Do other games work fine?

You have stated that you have "tried many ways" - please post a detailed description of the steps that you have tried ?

Could you send us a screenshot of device manager with display adapters expanded?

Keep us updated.

Hi Rishi,

Below is my configuration:

1. in Configure Switchable Graphic setting:

2. In Switchable Graphic Global Setting:

3. In devices manager:

4. When I use monitor function:

It show that pes2013 is running with high peformance processor. But pes setting and pes2013.exe still notify that there aren't enough VRAM. pes setting show only 32 Mb VRAM.

It seem that "high peformance" is 32Mb VRAM processor of Radeon HD 8790M and "Power saving mode" is Intel HD Graphic 4600 and I cannot use 2Gb VRAM processor.

I have another computer with much lower perfomance (CPU, RAM, GPU) but it still run this game very well.

I play only this game and haven't test another game.

This game is well known for working poorly or not at all with hybrid video systems.

There are plenty of references to the need to patch it

in order for it to work with hybrid video.

Hi ENJ63,

Thank you for your help.

I find out that this game cannot work with windows 8. It worked on windows 7 with same computer.

I will try your recommendation.

Thanks again.
