Crashing to Desktop (no error)

*EA App

You can try to delete the system shader's cache and AMD's ones. The locations for system's cache are c:\Users\[uername]\AppData\Local\cache\ and c:\Users\[uername]\AppData\Local\D3DSCache\

In addition, clean from time to time the %temp% folder and what is inside c:\windows\temp (admin rights required for last one). Example for cleaning temp files:

@echo off

pushd %temp%
for /d %%D in (*) do rd /s /q "%%D"
del /f /q *

pushd c:\windows\temp
for /d %%D in (*) do rd /s /q "%%D"
del /f /q *
popd

Save the code as  .bat file and call it from time to time to eliminate the ballast (part of maintenance routine). 

Unfortunately I don't know where AMD store it's shader cache but it sould be something similar to nvidia c:\Users\[uername]\AppData\Roaming\NVIDIA\ComputeCache  , c:\Users\[uername]\AppData\LocalLow\NVIDIA\PerDriverVersion\DXCache\

If you manage to find the exact location post it here in help for other AMD video card users.

Additional note, I clear all caches after each game update and when I'm done with one game and switch to another.

I think you're onto something with this, as it does seem more stable when the cache is clear, but having to wait five minutes for the shaders to load every time I boot the game is far from ideal.

I can't guarantee an improvement. It's just what I do after each video driver update, major windows update and as mentioned games updates or switch (overall about once every 2 weeks). The clean up temp files is on .bat file set up in schedule 30 min after log on, the cache clean up is another .bat file to be called on demand. Not sure it matters but not all shaders are build at game start-up and after cleaning system cache I expect the game to crash once or twice before get back to stable state. 

Did you found where AMD store the shaders cache?

Difficult to say.  A bunch of cache folders are held here - C:\Users\[User Name]\AppData\Local\AMD - but can't say for certain what relates to what.

Cache folders looks a bit like ab326b5a64fa2db7 or a similar mumbo-jumbo and inside there are some different mumo-jumbo like 6F75932F-7DFC-4FB0-B4B8-12DE1AC415DA_VEN_8086&DEV_9BC4&SUBSYS_1E91&REV_5 or F4EB2D6C-ED2B-4BDD-AD9D-F913287E6768. There are safe to remove. Important files (part of drivers or system files) have a explicit name (usually 8 characters or less). My new video card didn't arrive yet so for AMD I'm still at the guess stage but once I have it installed I will provide more information.

If you open event viewer:

C:\WINDOWS\system32\eventvwr.msc

Double click "Windows Logs" on the left hand side, and then click "Application" under it, it will come up with all the entries for your system regarding application errors and other information.

If you run Veilguard and can trigger a CTD, open the event viewer up as above and it should list exactly what happened that triggered the CTD. If you can copy and paste here what it says we might be able to help you figure out what is going on.

Are you skipping Dialogue conversations? ( space bar or mouse click button lower right corner )

If so, how often are you skilling dialogue?
If so, how fast are you skipping them?

I ask as I have at least twice with a left mouse button click speed estimated at least five clicks per second ( about 5.5 to 5.8 cps ), causing the game to crash to the desktop with zero error messages. 

One area where you can test this specifically is all the dialogue involved when you interrupt Solas's Ritual

Nothing currently showing for Veilguard specifically around the times it's happened, though can't remember exact times or dates, so can't say whether something on a system level caused it (it ran fine yesterday).

Will keep an eye on this, though.

I skip the occasional dialogue, but it has never crashed when doing so.  More often than not, it's during gameplay; usually when just wandering around.
