Literally Breaks Steam Games on Decent GPUs

After paying for Pro subscription to utilize my ipad with Mudbox and Photoshop, two GPU intensive pieces of software that this app is perfect for, I found that it was an amazing addition to my toolkit. Finally I could link my ipad to my pc and draw directly in my apps. Then I tried to load a game on steam and it loaded to a fully black screen. I tried another, same problem. It took me a week to figure out it was Duet Display on Windows 10. So I realized I had to either choose my multihundred dollar steam collection or a 20 dollar app.

I emailed Duet to see if they could refund me and if they knew about the problem. Apparently they are aware that 1000 series Nvidia GPU’s have issues with Duet. You know, the newest most powerful GPU’s you might use for 3D modeling, photoshop and that kind of thing. They apparently aren’t in charge of the subscription for their own product. Meaning that they can take my 20 additional dollars on top of the app, but that they can’t refund me when their product literally breaks a major component of my PC.

I am livid, please wait on buying this if you have a PC with a 1000 series Nvidia GPU. Don’t get scammed. Also, Apple, figure out how to let companies refund users if their app subscription causes this kind of problem. This is ridiculous.

It works beautifully.... until the cursor becomes out of sync.

I have downloaded this app about a week ago and it worked very brilliantly. However, all of a sudden, the moment I upgraded my iPad, now the cursor is touching the wrong way. I tried following the instructions on how to fix this problem on the website but I don’t have most of the particles it is telling me to use. I tried to downgrade my app but to no avail. I even went back to the Apple Store to see if they can fix this problem (by downgrading my iPad), but they said there was nothing they can do to fix it. I tried to contact duet display and still have yet to even get a response.

Just a warning to everyone, be careful if you purchase this app and do not upgrade your iPad Pro.

Kinda good tell one point..

I used it everyday. I had my game on one screen and discord on my iPad screen.
Tell one day I exited my game and my hole computer froze!! I had to restart the computer. You might think its just the computer BUT NO, I just bought this computer a month ago. It’s a BRAND NEW iMac and I just got this iPad PRO. For crying out loud just fix lag and crashing of the computer..
