Unable to activate GPU acceleration on the browser

So, yeah, what it says in the title. I tried searching for it, but the other cases I saw aren't exactly the same as mine.

No GPU acceleration at all is enabled in my browser. This is the vivaldi://gpu report:

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
CheckerImaging: Disabled
Flash: Software only. Hardware acceleration disabled
Flash Stage3D: Software only. Hardware acceleration disabled
Flash Stage3D Baseline profile: Software only. Hardware acceleration disabled
Compositing: Software only. Hardware acceleration disabled
Multiple Raster Threads: Enabled
Native GpuMemoryBuffers: Software only. Hardware acceleration disabled
Rasterization: Software only. Hardware acceleration disabled
Video Decode: Software only. Hardware acceleration disabled
WebGL: Software only, hardware acceleration unavailable
WebGL2: Software only, hardware acceleration unavailable

To compare, this is my chrome;//gpu report on Chrome 65:

Graphics Feature Status
Canvas: Hardware accelerated
CheckerImaging: Disabled
Flash: Hardware accelerated
Flash Stage3D: Hardware accelerated
Flash Stage3D Baseline profile: Hardware accelerated
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
Native GpuMemoryBuffers: Software only. Hardware acceleration disabled
Rasterization: Hardware accelerated
Video Decode: Hardware accelerated
WebGL: Hardware accelerated
WebGL2: Hardware accelerated

I'm on 1.15, latest version. Already tried to go to vivaldi://flags and enable "Override software rendering list" and "GPU Rasterization", to no avail.

The only extensions I'm using are nano adblocker, tampermonkey, stylish and lastpass (all of those are the same extensions I use on Chrome).

My laptop is one of those that uses dual graphics (an onboard Intel and a GeForce 940MX 2GB VRAM. I already configured the system to open Vivaldi using the GeForce adapter. Also, I'm on Windows 10.

Does anyone have any idea of what's happening, and what I can do to fix it?

OK, so I'll reply to my own thread saying that I found the answer.

Fiddling around, I saw someone saying that you should go to vivaldi://settings/content and then fiddle with some options. My problem is that I wasn't seeing anything that the persona was saying I should see.

So, it turns out that the real path is chrome://settings/content

This will lead to a different screen. Pressing the arrow on top will lead to an "all setting" page, and then scrolling all the way down I found the option to enable hardware acceleration.

There are those ways. A brazilian user was having the same problem and I had found for him those two solutions:

1- On the addressbar and pressing ENTER:
chrome://settings/?search=hardware
I dunno how is exactly in english but you will see some option written "Hardware Acceleration".

2- On the addressbar and pressing ENTER:
vivaldi://flags/#disable-accelerated-2d-canvas

I used the both ways and improved a bit the browser fluidity
