DDU Necessary?

[RGBisKey]

I plan on getting a new GPU soon, my question is is it absolutely necessary to DDU the drivers from the old card?

[Tan3l6]

No

But if errors appear then - Yes

Normlly not needed, you can just try it, bu DDU cn make it so weird issues are much less likely.

Quick and easy answer, I like it. Thanks.

It's certainly not a requirement to use DDU to completely remove all traces of your old driver off of your system and most of the times I just skip the step and uninstall normally through Device Manager without issues (usually). If a problem/s occur after installing the new card and it's drivers then I would try DDU and troubleshoot from there.

The answers here are very odd and very wrong. DDU is mandatory when changing the card else you are extremely likely to experience a varying degree of issues with performance, stability and even image quality/colors

I'd add disagree vote, as mostly there is no conflict when changing to different GPU.

I don't know why say it's mandatory? I've swapped about 20 graphics cards in the past 10 years, no conflicts. Rather more often conflicts appear after updating to new Windows 10 insider build.

 

The only inconvenience has been the control center of either nVidia or AMD being run on startup. So maybe removing drivers in regular uninstall method would be a good idea. Could use DDU, but if changing from AMD to AMD or nVidia to nVidia, there's usually no problem.

Every time you change the core architecture you o write a bunch of files, you change around a bunch of registry entries and the result can be mild yes or it can result in total OS corruption (has happened to me twice) so I would always advise DDau as a safe and sound method

That's complete BS...well, maybe for AMD I don't know...but Nvidia cards all use the same drivers..you can pop out a gtx 1080 and pop in a 2080ti and you don't even need to reinstall anything...and no you won't get any of the stuff you talk about.

Popped out a GTX 750 To, popped in a 960, I got into a GPU driver bsod loop. It's not bs at all, it's what happens when you don't clean up the mess Nvidia drivers create when hot swapping cards

I have only used it to roll back drivers and when upgrading/downgrading video cards.

 

With Nvidia cards I always download the driver and select Custom (Advanced), then click "Perform Clean Install" when doing updates.

 

I also run at least 2 older games before and after an update since they are the games that suffer the most from new drivers. That is usually a game that uses the havok physics engine(Skyrim or Fallout 3 or 4) and whatever isometric game(Xcom, Fallout) I have installed.

There was a time at I had to have a dedicated computer to play old games so it is important to me that they stay working properly.

never happened to me in over 15 years of using nvidia cards and building custom systems and upgrading machines for me, work, friends, clients and family...dunno where you're coming from with this, sorry!

It’s probably the fact you hot swapped cards lmao.

Yeah haha...it's better to at least power the system off lol

System was obviously powered off, hot swap as in not making a single software change.

From my experience, it is generally not necessary.

I tested GTX780, 960, 970, 1070, 1070ti, RTX2070s with exact same driver. All of them work properly.

I know it's an old topic, but the only correct answer is YES, without butts. Maybe it worked fine before but now if you change RTX 3000 series to 4000 and don't use DDU you'll basically have 3000 series performance with 4000 series GPU. If you don't use DDU there will be no errors but also you'll not have as good performance as you should

Fair point. Generational changes might need different drivers.
