Performance tips
If you're having lag (bad performance) then here you can find some tips that might improve it.
Recommended browser
For best performance, we recommend using Chrome.
This guide is also mainly aimed towards the Chrome browser.
Other browsers should have similar settings though.
Hardware Acceleration
Browsers some times turns this off, it’s really recommended to have this on to get way better performance.
Go to chrome://settings (type this in your address bar)
Then on the bottom select show advanced and search for System and ‘Use hardware acceleration’.
Make sure this is turned on.
If you go to chrome://gpu you can see if it’s enabled or not. (and there might be other issues shown here)
Performance mode
In your PC settings make sure energy saving is off and you have the power mode set to best performance. 
If you do not want to change this to reduce battery usage you can also go into your GPU settings.
There you will find the option to choose a power mode for each app so you can only set your browser to use best performance.
Video settings
In the settings menu (cog wheel) you can change your quality settings.
There are several settings that can be tweaked.
By default the quality is set automatically but if your game looks terrible or if you have bad performance the auto settings should be
turned off to manually override the settings.
Resolution scale
This changes the resolution the game is rendered at.
It can have a big impact on the performance if you scale it down.
Scaling it up can result in better looking graphics.
Quality multiplier
This is changes the overall rendering quality of the game rendering.
Reduce the multiplier to improve performance slightly.
Shadows, Particles, Anti-Aliasing
These settings can be turned on or off.
The amount of performance gain really defers per device and/or graphics card so just toggle them on/off and see if you get better performance or not.
Guest account on browser
By logging in as guest you will not have any extensions and/or plugins.
Not all browsers have this feature but if it does it’s recommended to use this.
It really depends on how many and which extensions you have enabled but it can drastically improve performance.
In the top bar click your user and select Guest.
Alternatively you can click Manage People and create a new user/person for CFP. 
Play the game in incognito window
This is similar to the point above but if your browser has no user management this another way to get similar results.
By playing the game in incognito extension/plugins are disabled by default.
Extensions/plugins can really consume a lot of processing power some times.
Play in windowed mode
By having a smaller window there is less pixels to render.
If you’re playing in windowed mode you can easily make the window smaller to reduce the screen size.
This can be used in combination with the quality settings so that you can make it not look blurry but still get good performance by playing in a smaller window.
Monitor refresh rate
Make sure your monitor’s refresh rate is set as high as possible.
The rendering of the game uses this, so if it’s set to 30 Hz it will render the game at 30fps.
Guide for windows: How to change monitor refresh rate
Guide for Mac: Go to System preferences- Monitor
You can also try uncap your FPS to get unlimited FPS, but this is usually not recommended.
Upgrade graphic card drivers
Please always make sure you have the latest drivers for your graphic card.
Use dedicated graphics card
Often the browser uses the integrated graphics card instead of the dedicated graphics card.
This only applies if you have a dedicated graphics card. (external GPU).
For Chrome you can write chrome://gpu in the address bar to see what GPU is used. (search for GL_RENDERER)
NVIDIA
- Open the control panel
- Select Manage 3D settings in the menu.
- Select Program Settings tab
- In the program selection select your browser like Chrome or Firefox
- In step 2 select High performance NVIDIA processor
- Restart your browser and verify it’s now using your dedicated graphic card
For other graphic cards search it up online for your card.
NVIDIA GPU Settings
For some further improvements you can try use the following GPU settings if you have an NVIDIA card.
- Vertical sync: OFF
- Triple buffering: ON
