Performance Issues

Some players experience performance issues and general problems in the game. This page lists all known problems and possible workarrounds.

### Known enhancements

The subpages of the Options page has info on increasing performance there.

For the stuff on main page during runs:

* Use autoskip rather than manual. Get it to 50 quickly (it costs a few waves, but increases SR/s)
* Turn knockback off
* Turn compress on (it costs waves, but increases SR/s a lot)
* (When you finally get it, turn Gravity Well off.)
* Turn gfx off

However weird it may sound, the game runs faster if you increase your screens refresh rate... In one case, switching from 60Hz to 144Hz increased WpM from 2200 to 2700.

### Known problems

#### Firefox

* Firefox throws an error and the game screen turns black
* The game runs very poorly and has an overall bad performance

#### Chrome

* The game runs very poorly and has an overall bad performance
* Export of the save game is not working properly (not able to copy the complete savegame to clipboard)

#### Edge

* The game runs very poorly and has an overall bad performance
* Edge allocates nearly all the RAM and uses nearly all CPU

#### Internet Explorer 11

* The game runs very poorly and has an overall bad performance

#### Opera/Opera Gx

* states doesn't support WebGl and yet it functions fine
* lags fairly often

#### General problems

* Savegame disappeared
* Game lags after many [auto]restarts
* Game freezes when not visible

### Possible Workarounds and fixes

1. Game runs poorly
	1. Set the ingame graphics to low or off
	2. Disable damage texts and combine damage texts
	3. Set the UI Opacity to zero
	4. Upgrade your browser to the newest version
	5. Try not to run too many concurrent windows
	6. If the option is available, go to Start > Choose a power plan > Additional Options > High Performance
2. Game error, game does not load
	1. Upgrade your browser to the newest version
	2. Check the version of possible plug-ins like Unity Web Player
	3. Check for plug-ins/add-ins that might block the game
	4. Try to use another browser
3. The game uses nearly all resources when using Edge
	1. This is a known problem to Microsoft already (since Edge is still under development it might be fixed someday)
	2. Change the browser
4. Chrome savegame export is not working
	1. Copy to clipboard does not work properly, because the maximum lenght of the copied text is fixed
	2. Use the "windows copy" instead -> window with game code opens, right click on the window, copy -> paste
5. Help, my savegame disappeared
	1. This normally happens, when you delete your cookies and/or internet data
	2. Switching browser or computer also means you don't have access to your old cookies anymore
	3. Check the settings of your browser, if it deletes all cookies after a certain time
	4. Check your computer for software like CC Cleaner and other "tuning software" which might delete your data
6. Games lags after many [auto]restarts
	1. No fixes per se, so periodically save game and refresh browser (ctrl+r)
7. Game freezes when not visible
	1. Run game in a separate window from the one you're surfing in
	2. Keep at least one pixel of the game visible at all time. That means no full-screen
	3. Changing 'Window occlusion'-settings may fix this, but they are usually experimental settings, so all the usual caveats apply. To do this, follow these steps:
		1. go to chrome://flags/
		2. find "Calculate window occlusion on Windows"
		3. set it to "Disabled"
		4. restart chrome
