As mac said:
- check the HDMI specs on your monitor and on the laptop. It will drop down to the lower spec. There is limited bandwidth and 144Mhz is a huge amount of data on that resolution. It might be that the laptop or the monitor doesn't support that refresh rate and that resolution for that HDMI spec. The Mhz means that 144 screens are sent every single second. Dropping it to 60Mhz is not noticeable unless you are playing twitch games.
The cable thing might not be an issue in other games since they are probably overriding the default refresh rate to whatever they can manage.
Are you using the correct graphics drivers? Old drivers massively dropped the performance. The new ones have since fixed it. I believe the way to check for this would be to go into console ( ' ), then type d3d_WindowsCursor (Press enter). This will turn off the thing that was causing the performance hit.
Another option could be enabling compatibility mode on your games. This should drop the system down to an older standard when playing the game. Be aware that Forged Alliance changed the settings after it closes. To get around this, I made a file that changed the compatibility settings before I run FAF.
Wow, you saved me. I solved the problem: the last NVidia driver... damn. Such a simple thing and I didn't notice this before at all.
Thank you Noob and Mac, you guys helped me a lot.
Yesterday I stayed all night long trying to solve the problem and today I was going to buy the displayport adapter that Mac suggested.
I updated the driver and boom, it worked perfectly. I didn't even need any changes at NVidia's panel to make it work and the best thing: all my games are running fluid now.
Just one last doubt: is there any gap between the 1.2 displayport cable that came from with the monitor and an adapter I may buy? I found an 1.8 adapter at Amazon and I don't know if I can buy it for two reasons:
If is there any gaps on adapter's use, 'cause the cable is a DP and my laptop's is a mini port (will I lose quality or something using the adapter)?
If is there any gaps if I use a higher or newer version of displayport adapter (to mini displayport) than that one from the monitor?
Thank you very much
