I am not convinced at this point that the keypress-delay is problematic. Do you have a particular use case, or simply text typing? <br> </tt><font size="2"><font face="Arial, Helvetica, sans-serif">Use case is any sort of regular typing in a VM, whether in gedit, vi in a terminal window, or typing an email in a browser window. It is a slight but noticeable delay when typing in the VM vs. on the physical host. The VM is running locally so I don't need there to be any delay to compensate for network conditions. <br> <br> In the link from 2014 I previously posted, the person who recompiled with 10ms value for keypress-delay saw a huge improvement in the overall feel. My hope for a solution is that the keypress-delay can be auto-tuned based on network conditions or user configurable. Thank you for considering this.</font></font><br> <tt> thanks <br> <br> <font size="2"><font face="Arial, Helvetica, sans-serif">Thanks,<br> <tt><font face="Arial, Helvetica, sans-serif">Jared Kwek</font></tt><br> </font></font></tt></pre> </div>  </div> </font>
