hi, thank you for your response, i’m running CS6, i have installed the latest updates, this is the laptop its on https://www.toshibadirect.com/td/b2c/cdetland.to?poid=2000098991 .. the only difference is i have 8 gigs ram.. the other specs are the same,

■Intel® Core™ i7-4700MQ quad core processor
■Windows 8
■8GB DDR3L memory
■500GB (5400RPM) hard drive
■NVIDIA® GeForce® GT 740M with Optimus™
■1920×1080 TruBrite display

quick time is installed

multi processing is on
do you need any more information?

Right click on the desktop and select the Nvidia Control panel. On the right you should have a Preferred Graphics Processor drop down. Change that to High Performance Nvidia Processor.

thanks so much for your response.. i just tried that but im not sure it helped.. i tested AE by playing with an effects-heavy project and after about 7 minutes it went black but only at 100% zoom.. if i zoomed in or out it went back to normal but if i went back to 100% it was black..

could it be my multiprocessing settings? right now its on 8 installed CPUs, 1 reserved for other applications, ram allocation per background cpu: 3 gb..

[Ericbowen]

Change the ram assignment per core to 1GB. What Nvidia driver are you running? Right click on the Desktop and select the Nvidia Control panel. Then select help at the top and select system information. Please list the Nvidia driver.

driver version: 311.41

[Ericbowen]

Download this driver:

https://www.geforce.com/drivers/results/63462

Select Custom install when it prompts. Check Mark Clean install and uncheck the Nvidia Experience and Framework if listed.

WOW ok actually im pretty sure the problem was my multiprocessing settings.. i changed it to 1 gb per cpu and i think that solved the problem! =D should i still download that driver? would it make AE faster?

[Ericbowen]

I would suggest the new driver. Just make sure to install as listed before.
