every once in a while in my life I encounter a computer or Electronics
0:05
issue that's completely inexplicable for example in the early 2000s I had a
0:10
machine that for some reason didn't
0:13
require the Warcraft 3 disc to be loaded in the optical drive I wasn't using an
0:17
OCD crack and the issue I'm not going to
0:20
call it a problem because it was very convenient the issue persisted over
0:24
multiple reformats and reinstallations of the game only to go away when I
0:29
upgraded the computer computer but the point of this video is not for me to
0:32
tell old stories from a million years ago because I'm old the point of this
0:36
video is that thanks to the power of video recording and the internet I can
0:41
now share with you these experiences
0:45
welcome to episode one of what we're calling haunted Hardware
1:05
tunnel bear is the simple VPN app that makes it easy to browse privately and
1:10
enjoy a more open internet to try tunnel bear for free check out the link in the
1:14
video description so you're sitting there at home thinking lus there's
1:18
nothing haunted about running doom on a computer it's supposed to work that way
1:22
the game is scary we not scary whatever the case may be no no the haunted thing
1:28
about what you're looking at right now is this fraps counter up here in the top
1:33
left corner that's not supposed to be there now if I was running an open GL
1:37
mode that would be fine but look at this
1:41
settings Advanced
1:45
Vulcan for contrast this is how it is
1:49
supposed to work this is my normal desktop test bench with a GTX 1080 we go
1:54
into settings Advanced openg 4.5 boom
1:58
FPS counters working now if we switch to Vulcan Doom will
2:03
restart and we'll fast forward through this if it drags out for too long for
2:07
you guys and my camera person will hold kind of still but really you can already
2:11
see okay we are switched over to Vulcan my FPS counter is gone fraps is still
2:17
very much loaded in the system tray it just doesn't work that way fraps isn't
2:22
designed to work with either of the new lower level apis that is Vulcan or
2:28
directx12 that what you just saw there is the
2:32
normal expected Behavior so it's at this stage in any troubleshooting process
2:37
that the good old sanity check comes in so you go into your settings you go this
2:41
is a really cool feature of Doom it's like it's almost like it's made by
2:46
people who care you go show performance metrics and you go okay is it actually
2:51
running
2:54
Vulcan yes it would appear so okay but if we were running in
3:01
borderless Window mode it is possible
3:04
that fraps could overlay itself in some
3:08
way so what we need to do is go into the
3:11
console and this is another great thing that Doom has and good games should all
3:17
have and we can have a look at what commands we have and we go okay vid
3:21
restart okay you saw that black flash no
3:24
the game is running 1920 x 1080 full screen so the next logical step let's
3:29
check our software revisions maybe NVIDIA has a driver or Doom released an
3:34
update or uh the fraps has a new version
3:38
something of which enables this functionality so NVIDIA driver 21213
3:44
7270 got it Doom build 127 2992 and
3:49
fraps is version 3.5.9 let's go double check all that
3:54
stuff over on the desktop here we've got that same driver revision it's great
3:58
even though we're running a different graphics card they're the same architecture running the same
4:02
driver Doom is running that exact same build which makes sense because I've
4:06
always got auto update enabled in Steam and finally fraps is running that same
4:12
3.5.9 in fact here's a fun fact I didn't realize this until I was working on this
4:16
video fraps hasn't even been updated since 26th of February 2013 so for them
4:22
to have introduced a patch that enables this functionality seems very very
4:27
unlikely considering the last patch fixed AO desktop and directex 10 games
4:34
so then it's at this point that we start getting into the troubleshooting steps
4:37
that take a little bit longer we're going to do a full reinstall of our
4:41
driver as well as Doom downloading a
4:44
completely fresh copy of the game off of steam just in case there is some weird
4:51
corruption that's not allowing it to properly launch in Vulcan mode for
4:56
example to get rid of our videoar driver we're going to be using ddu I'm not
5:00
going to go through all the steps in you know Exquisite detail but basically you
5:04
reboot in safe mood you run ddu you download a fresh copy of the drivers off
5:08
NVIDIA and install that and try
5:12
again and we're back in game now with
5:16
fresh drivers fresh copy of the game and
5:19
exactly the same behavior we saw last
5:24
time so at this point it's time to take
5:28
it to the next level we are going to do a fresh format of this PC we're going to
5:33
go back to bone stock then we're going to update the
5:37
drivers then we're going to install the game and see if it persists now I
5:43
suspect it's running in open GL mode out
5:46
of the box it's not something you can configure
5:50
when you launch the game for Doom so everything here looks hunky dory totally
5:55
normal open GL 4.5 we have
6:01
CS okay
6:04
Advanced Vulcan
6:10
yes 1100 frames per
6:15
second haunted right
6:19
haunted haunted computer ven
6:27
1.0.13 frame rate counter
6:30
working even though it shouldn't and the game is loading now I
6:36
did observe that openg Vulcan regardless
6:40
of what API it was running performance did look a little bit low there so I'm
6:45
going to remove another variable I'm going to disable the onboard Graphics
6:50
here disabling this will cause it to stop functioning you think that's good I
6:56
would sure hope so and what I'm going to do now is to determine once and for all
7:02
whether we have magic fraps or broken
7:06
game I am actually going to do our
7:09
Benchmark run with each different
7:13
readout here and see if they perform
7:19
differently okay so settings we're going
7:23
to Triple confirm them blah blah blah blah blah full
7:28
screen blah blah BL blah Advanced Vulcan
7:31
definitely everything is wow wow
7:37
Windows okay I'm not going to run the whole Benchmark because quite frankly
7:41
the difference between Vulcan and openg GL at this resolution on this Hardware
7:46
should be pretty much immediately noticeable so we're getting about 70
7:50
frames per second talking to this guy
7:53
respectfully um so that's fine let's go
7:57
ahead settings advanced open
8:02
G
8:06
restart okay here we
8:09
go no way okay hold on just a second
8:15
here what the sh just happened okay so at this point
8:22
in the video I was kind of expecting the conclusion to be haha it's just running
8:28
open GL because the game isn't launching in Vulcan
8:33
mode but what we appear to have gotten
8:36
instead and I don't have another 1060
8:40
equipped laptop to compare against unfortunately but we what we what we
8:43
appear to have gotten instead is magical fraps running on a
8:48
magical machine magically working on Vulcan even though there is absolutely
8:52
no way and I'm sure the fraps developers would be happy to call me up and tell me this personally there's absolutely no
8:57
way that this is working so this is the kind of that I go through all I wanted
9:04
all I wanted was a performance
9:07
comparison between this laptop and this
9:11
laptop for my review of this
9:16
laptop this is what I'm dealing with so
9:19
if you were wondering when you saw the review of this laptop which will perhaps
9:23
come out before this video why there was no Vulcan Doom testing now you know I
9:29
don't know blaming this laptop in fact I probably won't even mention it because
9:33
it's probably not this laptop's fault because I've seen this kind of
9:36
before I'm just happy that for once I got to share the experience with you
9:41
guys you know I'm really glad that fresh books is the ad spot on this video
9:45

9:49
a checkbook that won't balance or like
9:52
