Cannot open Call of Duty Modern Warfare - have eliminated the game and it's servers. Issue must be on my side.

Hi Jeramiah, Check this out

If it still the same, I'd suggest to contact with Activision.

Thank you for the reply, I did contact Activision Support, after a 2.5 hour wait, I was given the instructions of what I wrote as completed TS steps.
Now I'm at this step with no idea how to proceed..
I followed your link and did the following:

1. Update Drivers from GeForce Experience

2. Delete Players Folder from Directory (Since I've never opened the game, this doesn't exist to delete)

3. Change Value in the Registry Editor

4. Use an Additional Command Argument

None of the above worked sadly.
Anyone else have any ideas?

- It's hard getting details about the game. The sites are so hyped up with marketing and grand images.

(Whoa! 175 GB storage space ? I thought Red Dead 2 was big.)

Are you having problems with both the COD-MW single player campaign, or only the COD-MW multi-player\COOP,

and  COD-MW: Warzone season 5 ?

- If you are running other games without similar problems Windows is not likely at fault (unless the new season requires Win10 v2004

and you are still on Win10 v1903 ?), but it looks like you have covered the more common fix suggestions.

If a lot of people at the COD forums are having multi-player problems since a recent multi-player\battle-royal update the

update may be the cause of your problems ?

- What brand and model cpu, and what model Nvidia gpu does you machine use ?  Laptop or Desktop ?

- I doubt the game would launch successfully using an integrated gpu as the game requirements specify a minimum of 2GB VRAM

Is the game trying to launch using your machines integrated graphics (sounds like laptop then). If so, are you able to verify

if the game is actually managing to switch to the Nvidia gpu ?
If not ... GPU-Z Video card GPU Information Utility  may be helpful.

- Do you have GeForce Experience installed ? If so, this may be conflicting with your Control Panel settings. The Experience

has also been know to cause problem with some games in the past too.

- Or, if you are using a Desktop machine you could try disabling the integrated graphics via Device Manager > Display Adapters

(reboot may be required), or in BIOS. This should force the machine to boot using the dedicated gpu.

This may not be possible with laptops though as they are designed to boot with the integrated gpu to save power.

- Is the Command Line you tried in the games shortcut Target box ? If so, did you leave a space between end of the target and -d3d11 ?

(I don't imagine it would help if the game has never been launched though, as the game would normally default to DX11 settings first time.)

Have you re-set this and the Registry tweaks back to original when they didn't work ?

btw -

"Tried running VRAM under maximum and default settings."

- Are you speaking of the system RAM that gets allocated to an integrated graphics processor that mfg's of laptops

often refer to as Video RAM ?  This is not actually VRAM.

VRAM is only found on your dedicated gpu and there are no settings for changing VRAM.

"I don't have any sort of Overly software"

- Overlays are found in various gaming client software, such as Steam, UPlay, EPIC and EA Origin.

Overlays are sometimes enabled by default and have been known to cause problems with some games, but not so much

with games released in the past few years.

In Steam the overlay options can be found in your Steam clients  Settings > In-Game  tab.

The other game client software have similar options.

.

Just so we're clear on what happens - the above is taken live from my computer, when I click on Play - it show's launching, Goes back to Play.

And each time I do this, there is an EVENT LOG

 ----------------------------------------------------

- (Whoa! 175 GB storage space ? I thought Red Dead 2 was big.) Actually 224 GB is the opening install amount - ugh!

Are you having problems with both the COD-MW single player campaign, or only the COD-MW multi-player\COOP,

and  COD-MW: Warzone season 5 ?  I have never even opened the game.  The exe. I'm opening is the full COD-MW Full Game. - I don't have different exe's for single player or MP.

- If you are running other games without similar problems Windows is not likely at fault (unless the new season requires Win10 v2004

and you are still on Win10 v1903 ?), but it looks like you have covered the more common fix suggestions.

This was not suggested anywhere - I am still on v1903 - I will update to v2004

If a lot of people at the COD forums are having multi-player problems since a recent multi-player\battle-royal update the

update may be the cause of your problems ?  As far as I can tell, many people have had this same problem, and NONE of the original posters of those problems have come back saying it was fixed.   There are always plenty of people posting that XYZ worked for them but who knows if that's BS or not?

- What brand and model CPU, and what model NVIDIA GPU does you machine use ?  Laptop or Desktop ?

Desktop

AMD Athlon II x4 640 Processor 3.00 GHz

24 GB RAM

GeForce GTX 980 Ti GPU

6GB of VRAM 

- I doubt the game would launch successfully using an integrated GPU as the game requirements specify a minimum of 2GB VRAM

Is the game trying to launch using your machines integrated graphics (sounds like laptop then). If so, are you able to verify

if the game is actually managing to switch to the NVIDIA GPU ?
If not ... GPU-Z Video card GPU Information Utility  may be helpful.  I went into the NVIDIA control panel and forced the computer to choose the NVIDIA card. 

- Do you have GeForce Experience installed ? If so, this may be conflicting with your Control Panel settings. The Experience

has also been know to cause problem with some games in the past too. I do have GeForce Experience - but the Clean Boot I spoke about above bypasses this program.

- Or, if you are using a Desktop machine you could try disabling the integrated graphics via Device Manager > Display Adapters

(reboot may be required), or in BIOS. This should force the machine to boot using the dedicated gpu.

This may not be possible with laptops though as they are designed to boot with the integrated gpu to save power.

N/A

- Is the Command Line you tried in the games shortcut Target box ? If so, did you leave a space between end of the target and -d3d11 ?  The command line was placed within the Blizzard Launcher, and I have verified just now that there are no spaces... but good thought!

(I don't imagine it would help if the game has never been launched though, as the game would normally default to DX11 settings first time.)

Have you re-set this and the Registry tweaks back to original when they didn't work ?  Yes - reset

btw -

"Tried running VRAM under maximum and default settings."

- Are you speaking of the system RAM that gets allocated to an integrated graphics processor that mfg's of laptops

often refer to as Video RAM ?  This is not actually VRAM.

VRAM is only found on your dedicated gpu and there are no settings for changing VRAM.

This was a request by Activision support, and I intrepreted this to go into the NVIDIA control panel and change the amount of VRAM allocated to the game... to be honest I didn't really find anything.   But from my research there really wasn't anything I could do.   This TS step should be ignored :-)

"I don't have any sort of Overly software"

- Overlays are found in various gaming client software, such as Steam, UPlay, EPIC and EA Origin.

Overlays are sometimes enabled by default and have been known to cause problems with some games, but not so much

with games released in the past few years.

In Steam the overlay options can be found in your Steam clients  Settings > In-Game  tab.

The other game client software have similar options.
The Clean Boot bypasses the overlay possibility

Thank you very much for your continued help with this.
I appreciate it very very much!

- OK then. Desktops should never try to launch a game using their integrated graphics (which, judging by the cpu, I expect would

be on the mobo  with your machine), because they should only be able to use the igpu if it is connected to a monitor .

- Clean Boot may bypass the overlay if you have the Blizzard (or similar) client set up to launch with Windows at startup.

But if your game clients only load when you launch a game (what I do), Clean Boot won't help as it only works with

Services and Startup programs.Regardless, disabling the overlay from the clients settings may still be worth a try.

- Ah! Right, I forgot Steam and other client software have this Command Line option. I don't often launch games from

my Libraries in Steam, etc. A space is not required in this instance. Only when using a Desktop shortcut.
I reckon there should be no issue using DX12 effects games with an Nvidia 900 series card, as they are fully DX12 compatible.

Unless the game has a bug (maybe due to update ?) in it's DX12 effects.

- How is your 24GB RAM configured ? Have you added 2X4GB to 2X8GB or the other way around ? Whichever is the case,

try removing the 8GB just to verify the mismatched RAM is not involved.

I've yet to come on a game that comes close to using 16GB System RAM with my normal background app load out.

But if you were to have a bunch of other stuff loaded in the background that brings the RAM use to 16+ GB,

that may be part of the problem.

- Or...

Your cpu (the AthlonII series), is getting a bit long in the tooth, and I expect there were never any dedicated cpu related Win10 drivers

released by the mfg of your motherboard.

I had a machine with a Phenom II 965 and even didn't bother trying to install Win10 (5 yrs ago) on that machine because of this.

Problem is, yes Windows Updates may install suitable generic drivers and they may work with most things, but no guarantee

of full performance. Particularly with newer game technologies.

Leaving that aside (and putting my 1st pick last), the games minimum cpu requirements is for an FX-6300 which has a base speed of

3500MHz w/ 4100MHz turbo boost, vs 3000MHz on your Athlon II 640, so the game may be rejecting the cpu, causing it to stop loading ?

- All the RAM, cpu stuff are more about best practice, so none of the above may actually be the source of your evil in this instance.

But as the problem is only with the one game... Murphy's Law may have been invoked ...

.

Thank you all for the help and advice.
No one ever comes back to say what the finale is of their issue.

Well, I gave up.
I got in contact with Blizzard and requested a refund.

Pro tip - Blizzard and Activision have a 3 day refund policy.
Buy a game and keep it 3 days, you own it forever.
My only saving grace was it was 3.5 days and I had never actually opened the game up.

Good luck out there if you have this problem.  I was never able to get it to work.

Cheers
