Guide | Vivaldi on 🐌 Old / Low End Computers

The %U is mentioned here

It seems we have to test between the Flags and Switches till find the best set up.

There is a flag #ignore-gpu-blocklist that overrides the software rendering list and enables GPU-acceleration on unsupported system configurations. I'm going to remove the two switches, enable this flag and relaunch it to see if there's a difference.

Looking at vivaldi://gpu afterwards, with the exception of the command line, initialization time and the log messages, the information was the same, with hardware acceleration enabled and with the flag either enabled or disabled.

This is the GPU:

The only item it doesn't support is DirectX 11 and above. Seems to be a pretty basic GPU.

Here there's an Intel HD3000 and GMA 950
They work enough fine with those 2 Switches and the GPU Flag.

HW/A Enabled on both

Not deeply tested to find differences on the set up beyond what's mentioned in the first post.

@Zalex108 With the switches and that flag enabled, with HW/A also enabled, the images on Ars Technica are the same, still degraded. No difference.

If the switches come off (normal Vivaldi launch) with HW/A enabled, whether or not that flag is enabled or disabled, the images are fine.

I'll check here

@Zalex108 On a standard launch with HW/A enabled, with #ignore-gpu-blocklist enabled or disabled, the graphics information on vivaldi://gpu remains the same:

Graphics Feature Status
Canvas: Hardware accelerated
Canvas out-of-process rasterization: Disabled
Direct Rendering Display Compositor: Disabled
Compositing: Hardware accelerated
Multiple Raster Threads: Disabled
OpenGL: Enabled
Rasterization: Hardware accelerated
Raw Draw: Disabled
Video Decode: Hardware accelerated
Video Encode: Software only. Hardware acceleration disabled
Vulkan: Disabled
WebGL: Hardware accelerated
WebGL2: Hardware accelerated
WebGPU: Disabled

@edwardp

Then your's would not be on the Black List.

@Zalex108 That's interesting. I figured today, it would have been, since it's exactly not a new GPU.

The motherboard in this desktop only has two closed PCI-Express x1 ports. In the past, I've tried using x1 video cards with either an nVIDIA or AMD Radeon chip on them, but Linux would not boot up into the desktop with either of them, X reported 'no screens found'. I am aware that some video cards only work with UEFI systems, not BIOS and that could be the reason why.

Zalex108

@edwardp

First notice about that limitation.

@Zalex108 Here's one example:

https://www.techpowerup.com/forums/threads/graphics-card-with-uefi-only-bios-and-system-motherboard-non-uefi-will-not-post.230500/

The nVIDIA card that I tried, is also by Zotac and has nVIDIA's GT-710 GPU on it. If the x1 ports were 'open-ended', I'd be able to try an x16 video card.

My other desktop which is two years older than this, has an integrated nVIDIA GeForce 6150 SE / nForce 430 on that motherboard, but it has x1, x16 and legacy PCI ports. I installed a VisionTek video card with an AMD Radeon HD 5450 on it, in the x16 port and that card works perfectly.

There is a process-per-site flag, not sure if it's the same as the (generic?) --process-per-site switch:

I am going to test this to see if there is a noticeable difference in speed. Although the desktops are now 15 and 13 years old, VIvaldi runs fine on both, without any flags set.

Hibernation

Despite the Default Hibernation, some Extensions allows to keep the Tabs Sleeping even when gains focus.

TabSuspender - Preferred

New TabDiscard - On 2021 it wakes the Tabs on focus

The "New" TabDiscard just links to the GitHub page for TabSuspender, which hasn't been updated in 7 years.

Here are correct links for what I believe you had intended (same author as TabSuspender):

@Zalex108 You might want to add the builtin way ( chrome://settings/performance ) to the guide as alternative to the extensions (I don't know if they blend well together). Probably chromium enable it on low-ends but unsure..

Zalex108

@Hadden89

Thx!

I have it on my Systems and it works.
Not Scientificlly tested but not seen any drawbacks.

I'll add it in the next days.
Thx

Hi,
There, is explained about the old and new version.
It points to the current one

I have enabled the GPU Rasterization flag (#enable-gpu-rasterization) on my 13-year old Linux desktop, as a test.

This PC World article includes a basic description of rasterization. With this flag set to Enabled (then restarting Vivaldi), it offloads this process from the computer's CPU to the GPU.

I did some tests on one of the machines since having Blurred Fonts but didn't noticed anything.

Anyway,
It would help on some systems.

I'll add it later.
Thx

@Zalex108 The display resolution should also have an effect. I have the resolution set to 1920x1080, which is Full HD. The monitor is a 22-inch Samsung.
