Mouse input lag with driver / gpu manufacturer difference ?

[BradOZman]

ve always been an AMD fanboy but now Im thinking my next upgrade might be nvidia...

Right now I have an AMD and an Nvidia card in the same machine (friend gave me his old nvidia card). When I plug the monitor cable into the Nvidia card I instantly notice it feels better in windows. The difference visually is incredibly slight but makes a huge difference in how good it feels.

Although I am using the standard driver that windows gave me and also I have noticed more mouse lag between Win10 and Win7 before putting the extra nvidia card in. This may also be because of a driver problem. In win7 use an old AMD driver Catalyst v14.2 (i think) and in Win10 I downloaded the latest AMD Crimson driver with all the new features like VSR and the overclocking features removed.

Im going to try updating the nvidia drivers now and see if theirs a difference. (since Paragon game just told me this driver has issues)

May it's just newer driver have too many features and things going on. I dont know too much about how driver work tbh but I can definitely notice the slightest difference in input lag. And the upgrade to win10 was a massive lag increase (massive in my terms most ppl dont notice it) witch is what started me down this road to find a solution.

Ive done a LOT of different things and reduced the input lag significantly in win10, but was still noticing an improvement when booting back into win7 with old drivers. And even then more difference when switching to nvidia. (still using default win7 nvidia driver)

So.. maybe my AMD fanboy days are over... not sure. I do miss the slightly sharper and more vibrant display of AMD but if I play better with Nvidia thats the way Im going.

This might be really difficult to answer but can anyone figure out what cause this problem before I fork out for my next upgrade?

You cannot run both sets of video card drivers at once. The only possible exception might be with Windows 10, and still have not seen any articles showing where they actually tested that. So I would take that as meaning that the people that test hardware have not yet succeeded when attempting to run video cards from both companies in the same system at the same time.

Doing what you are attempting to do has never been possible before. And it may well still not be possible.

Two video cards with the same GPU and same amounts of memory can sometimes work.

Two cards from different companies has been a dream for gamers, but I have yet to see anyone actually manage to do this and be stable.

Don't blame one company or another, especially when what you are attempting to do has never, ever worked before.

Well its got nothing to do with that though. I experience the same thing on my laptop with only AMD. I experienced it on my desktop BEFORE puting the nvidia gpu along with the radeon.

Its not a question of weather running 2 gpu's is a problem because its not. It's a question about why AMD has input lag.
