New graphics card - low graphics memory ?

severedsolo said:

What is the screen refresh rate you have set? Also, what is the right screen refresh rate for your monitor? (you can check this in Nvidia Control Panel) usually flickering screen is a bad refresh rate.

Also, check the games are set to the same refresh rate in Graphic options

refresh rates set to 75 both in game and monitor.

I feel its the GFX can't keep up =/ even though with the older motherboard it ran like a dream ?

When you say flickering, do you mean the screen is physically flickering? Or you are getting framerate lag?

If you could fill out the rest of your System Specs https://www.sevenforums.com/profile.php?do=extra, we may be able to help you further

I have a feeling It's framerate lag, which makes sense as reducing game resolution or un-checking full screen does reduce the amount it happens.

Started when I changed my motherboard from the asus m4a78 to the m5a78L.

I've also updated all the spec's for the link you gave me

Thanks
