FPS fix for Valheim

The steps are simple:

Right click on Valheim in your Steam library and go to ‘Manage’ and then ‘Browse local files.’
That should bring up a window of Valheim’s game files.

Click on the valheim_Data folder.
Find the file named ‘boot’ or ‘boot.config’ and open it with Notepad.
Add “gfx-enable-gfx-jobs=1” as a separate line at the very top.
Add “gfx-enable-native-gfx-jobs=1” right below the first line.
Save and close the file.

Go back to Valheim in your Steam library, right click and select ‘Properties.’
Add “-windows-mode exclusive” into the launch options field.
Close that window.

Open up Task Manager (press Ctrl + Alt + Delete) and find Valheim under the processes tab.
Right click and select ‘Go to details.’
Right click valheim.exe, select ‘Set Priority’ and change it to ‘High.’
You’ll have to repeat this final step with Task Manager each time you launch the game.

SWITCH OFFICE 2016 TO MONTHLY TARGETED CHANNEL

The Office 365 ProPlus update model supports 4 production channels;

  • Monthly Channel (Targeted),
  • Monthly Channel,
  • Semi-annual Channel (Targeted),
  • Semi-annual Channel.

Each channel receives features updates, security and non-security updates on different release intervals.

Consider a scenario where Office 365 ProPlus is installed on a machine from the Semi-Annual Channel.  Now let’s say, a new feature is introduced on the Monthly Channel which you would like to get.  Since you are on the Semi-Annual Channel you will have to wait for a few months before this feature is made available to the Semi-Annual Channel.  But what if you do not want to wait that long?  The answer is, switch to the Monthly Channel.

Switch Channels

Below are the steps to switch channels:

  1. Identify the channel which you would like to switch to. Features and updates by channel are documented here.
  2. Launch Command Prompt as an administrator.
  3. Navigate to “C:\Program Files\Common Files\Microsoft Shared\ClickToRun\”
  4. Run the following command to change the desired channel, let’s say Monthly Channel Targeted “OfficeC2RClient.exe /changesetting Channel=Insiders” (When running in powershell the command will be “.\OfficeC2RClient.exe /changesetting Channel=Insiders”

or if you want to switch to the Montly channel:

OfficeC2RClient.exe /changesetting Channel=Monthly”

Note – You can use this command to switch to any channel using the corresponding Channel keyword listed below:

Channel Keyword in CMD or ODT
  Monthly Channel (Targeted)   Channel=”Insiders” or Channel=”FirstReleaseCurrent
  Monthly Channel   Channel=”Monthly” or Channel=”Current
  Semi-annual Channel (Targeted)   Channel=”Targeted” or Channel=”FirstReleaseDeferred
  Semi-annual Channel   Channel=”Broad” or Channel=”Deferred

To start the switch Channel process, run “OfficeC2RClient.exe /update user” from the cmd prompt path “C:\Program Files\Common Files\Microsoft Shared\ClickToRun>” This should be followed by a series of windows which will take you through the process of downloading and installing updates for the new channel that you have switch to.

Speed up Synology SHR Raid repair.

Rebuilding SHR arrays can take a long long time.
But we can solve this by the might SSH / CLI.

SSH into your DiskStation. To view the status of your rebuild:

$ cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] 
md2 : active raid5 sdd5[6] sda5[5] sde5[7] sdc5[2] sdb5[1]
      7795118592 blocks super 1.2 level 5, 64k chunk, algorithm 2 [5/4] [UUU_U]
      [=>...................]  recovery =  5.2% (103271424/1948779648) finish=672.9min speed=45708K/sec

Initially, the rebuild speed is 45708 Kb/sec (~45 Mb/sec), with an estimated completion time of 670 minutes, or 11 hours so so.

We can go faster!

RAID rebuilds are speed limited. The default minimum and maximum speeds are, in Kb/sec:

$ cat /proc/sys/dev/raid/speed_limit_max # maximum speed
200000
$ cat /proc/sys/dev/raid/speed_limit_min
1000

Let’s increase that minimum speed a touch:

$ sudo su
# echo 50000 > /proc/sys/dev/raid/speed_limit_min

And see if we’re going any faster:

# cat /proc/mdstat 
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] 
md2 : active raid5 sdd5[6] sda5[5] sde5[7] sdc5[2] sdb5[1]
      7795118592 blocks super 1.2 level 5, 64k chunk, algorithm 2 [5/4] [UUU_U]
      [=>...................]  recovery =  7.3% (142689152/1948779648) finish=543.4min speed=55388K/sec

Yeah, it’s a little faster – up to 55 Mb/sec with an estimated completion two hours sooner.

# echo 100000 > /proc/sys/dev/raid/speed_limit_min
# cat /proc/mdstat 
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] 
md2 : active raid5 sdd5[6] sda5[5] sde5[7] sdc5[2] sdb5[1]
      7795118592 blocks super 1.2 level 5, 64k chunk, algorithm 2 [5/4] [UUU_U]
      [=>...................]  recovery =  8.4% (163878932/1948779648) finish=356.4min speed=83448K/sec

I played around, and with a speed_limit_min value of 100000, we hit a bottleneck and max out at about 85 Mb/sec, but thats pretty much twice as fast as we were going. Not bad. (Note to self: return to default value when the rebuild is finish.

Colourfull CLI

The Bashrc file controls the options in your terminal.
In order to open that file enter the following command:

  • sudo nano ~/.bashrc

Look for the line and uncomment it:

#force_color_prompt=yes

to be:

  • force_color_prompt=yes

save then execute source ~/.bashrc

When you reconnect to your terminal, you should see some fancy colours.
