3D Textures problem on my m11x

I've own this m11xr2 for 2 months and everything was normal, but 2 days ago while I was playing I noticed something weird... everything was maxed out but 2 minutes later the textures of the game were on low quality :/ (only the textures, everything else was fine)

Now everytime I play the game runs fine but after 5~20 minutes the textures goes from high quality to low quality with no reason.

I did a system recovery, reinstalled the GPU drivers, removed the overclock of the GPU, but it doesn't fix anything.

Does anyone know if this is a hardware problem?, I've only tested this with one game (which I play all day long).

 

Which game? What drivers are you running? Need more info.

 

TERA Online (Unreal Engine 3)

Drivers: 266.58 WHQL

 

Help please I hate playing with these low quality textures >:

 

Did you try setting the CPU/Ram overclock back to stock?

Most of these come with 800MHZ DDR3 ram, and when running at 1GHZ (which is what the ram runs at when the FSB is set to 166) it can cause lock ups, texture errors, as well as numerous other "weird" issues.

 

thanks, but it didn't work u.u

 

Actually R1s and R2 both come with either 1066 or 1333MHz RAM installed. 800MHz is a limitation of the ULV processors, not the chipset or the memory installed by Dell.
