WebGL

For some people different browsers work better than others in terms of frame rate and performance.
But it is what it is and not everyone can run WebGL straight out of the box it needs Hardware Acceleration in order to run.

You can check whether WebGL works at: http://doesmybrowsersupportwebgl.com

Common problems & fixes.

Chrome:
On Win XP, WebGL and acceleration is blacklisted because it causes various (serious) system crashes.
http://code.google.com/p/chromium/issues/detail?id=72975

However, to enable it anyway:

1) Close any open Chrome windows
2) Find the Chrome shortcut you use (normally on the desktop or in the start menu) and right click on it.
3) Select 'Properties'
4) Add the flag --ignore-gpu-blacklist at the end of the Target box

If that doesn't work type "about:flags" on address bar of google chrome
then under "Override software rendering list" Double click to "enable"
"relaunch google chrome" it should work now.

The above applies to systems running Vista, Win7, Win8/8.1 & Win10 as well.

Firefox/Waterfox/Palemoon:
WebGL and acceleration is blacklisted in some graphic cards.

Type about:config in address bar and make the following changes:

To enable WebGL, set webgl.force-enabled to true. "Double Click"
To enable Layers Acceleration, set layers.acceleration.force-enabled to true "Double Click"
To enable Direct2D, set gfx.direct2d.force-enabled to true "Double Click"
To enable Hardware detection, set media.hardware-video-decoding.failed to false "Double Click"

The above applies to all systems running WinXP, Vista, Win7, Win8/8.1 & Win10.

Other Versions of browsers to try if above doesn't help.
Chrome Beta https://www.google.com/chrome/browser/beta.html
Developer Firefox https://www.mozilla.org/en-US/firefox/developer

Edge Browser for Win10
Type about:flags in the address bar & tick the following boxes:

Unrestricted memory consumption
Experimental H264/AVC support

If still experiencing problems check you have the latest graphic drivers for your system. some links:

My laptop out of the shop is WinXP Pro 32-bit
But I'm running Win10 Pro 64-bit with default drivers set by windows & I can view races.

3 Tabs open GameApp/Race/Forum in a browser that has zero plugins.


Ignore the 60% wrote at the top and focus on the actual amount the game is using in the browser.

Cheers, James. Worked a treat! Seems to have solved my issues with the race viewer.

Interesting theory Kevin. Internet speeds might be part of the problem I don't have Fibre Broadband I just have normal bog Standard Broadband . First two races I had lag issues Germany & Hungary. European race I had a little, Spa I had next to none.

My laptop is far from high spec. and I use a wireless internet connection.

I have 2 desktop computers, the first one is correct and not lagging during races, the other one is pretty bad but can launch the race without errors and if I mininize the window without lags. I have a 2Mbps connection ..

I did the steps but the race viewer just isnt loading?

What browser Ben?

Firefox. Just changed now to try it on Microsoft Edge.

In firefox go to about:support and make sure Hardware H264 Decoding = Yes
Even the Edge browser will fail to load the race viewer if you do not have hardware acceleration on your system.

To try and force Hardware H264 Decoding = Yes

In Firefox about:config

media.hardware-video-decoding.force-enabled = true
network.http.rendering-critical-requests-prioritization = true
gfx.font_rendering.directwrite.use_gdi_table_loading = true

I tried all those config changes and still NAY :(
I get a YAY on Chome but it's an old version (17?) and it just puts up an alert about URL: LINE:0 ??

gfx.work-around-driver-bugs = true
browser.cache.disk.hashstats_reported = 0 (default is 1 but you dont want it)
browser.cache.frecency_experiment = 3 (default is 1)

i have Chrome running in my win XP. my video adapter does not support webgl but chrome manages to show the race viewer.
in beta, after the step back in development (when was really slow for everyone) it started to run perfect. with no lag at all, and not much CPU or RAM usage.
now, i cant manage to use firefox, and chrome is lagging as hell.
im out of 2 of my three leagues because is painfull to see but not be able to manage. i'm testing on this user, tuesday thursdays and saturdays, the other days im spectating but i'm really not in the mood at the moment. didn't thought this was going to be the issue. i thought we were going to be balancing and improving.

Must also remember that firefox and chrome have released two updated versions of their browsers since beta and they have blocked and removed items in config settings. If you can remember what the flags where that you used before during beta you can manually create it yourself and add them to the list.

nope, in windows XP still the same. I didn't update because it wont let me.
I followed all the flags you mention, and were already like that.

in my laptops runs better (it is just for working so, i cant risk it) but i did test it,
AMD turion x2 usltra dual-core mobile zm-82 2.2ghz
4GB ram
win 7
video
ATI mobility radeon HD3650

and.... chrome


can any of those flags make me use this amount of resourses?
