Pale Moon forum

Hello,

on my new MSI laptop with Core i7 6700HQ (Skylake) , Nvidia GTX960M 2 GB and 16GB RAM (Windows 7 PRO x64bit) , Palemoon lagging and stuttering much more than on my older Lenovo laptop with i5 3210M (Ivy Bridge) . Youtube or any HTML5 players (only players, videos are OK) lagging too (click to fullscreen takes 2-5 seconds) . Scrolling sometimes bad too (stuttering and very often “jumping“ ) .
Laptop and HW is OK, because when I try other browsers (Opera, Chrome, Firefox, IE, ... ) they are run faster than Palemoon (clear, portable, unstable) .
Thank you in advance.

It's more likely the NV 960 chip that's the problem here. There have been multiple issues with that particular chip, especially in hybrid setups.
You should make sure that Pale Moon uses the Intel graphics part of the CPU rather than the NV chip for its accelerated rendering.

I am sure, because this laptop has got an LED in power button, which when is red, that means, that Nvidia graphic card is in use.
And Nvidia control panel not shows me any activity about Palemoon.

So Palemoon runs only via the Skylake CPU.

Please post the output of help -> troubleshooting information (copy text to clipboard button, then paste in your reply)

Ok here you are.

Ugh. Intel's HD530 isn't the best either (plenty of issues with Gecko as well, according to bugzilla).
You can try disabling Direct2d and see if that helps. You can also try enabling the NVidia GPU for Pale Moon, and see how that works for you.
Sorry that this is trial&error, but it's a combination of 2 chips that both don't play nice with a Gecko/Goanna style renderer.

Ok thanks, bad news for me well :-/ ? And will be there any fix in the future?

Btw. with Nvidia GPU, Palemoon works smoothly and better, but right click context menu is slow when I moving cursor over it. But this problem I had on previous Lenovo laptop too.

It's not that simple to "make a fix" for. Hybrid setups like that are very tricky.

Ok, thank you for quick reply.

I installed Palemoon Commander add-on and on Grapgic - Rendering tab I uncheck Disable Direct2D acc. and Use Direct2D v1.1 when available. Then I checked Layers acc. forced.
This makes my Palemoon much faster (50-60%) and works on two monitors better . It's not fast as Opera or the newest Firefox, but it's really really better.

Wow its magic, its really faster now .

I think the issue is rooted in Direct2D on your setup. Disabling that likely avoid the bad driver code that slows things down.

I think the Layers force acceleration speed up my Palemoon much more.

Layers acceleration should already be on by default, so forcing it will likely do very little.

And I don't know, whether is this problem is Skylake compatibility, but when I play video on youtube, it starts drain my CPU on 60-70% (only on 60FPS videos) and video sometimes stuttering (not play smoothly on 60FPS) . And I have Core i7 6700HQ CPU. Opera takes max 20%. Thank you in advance.

Ok, so I wrote on Intel support, they finding a solution for Skylake and Windows 7 x64bit. They maybe will release new driver for it.
If you have Intel account, there is a thread https://communities.intel.com/thread/119375 , I hope, that this problem is in drivers.
