Dell XPS 15 (9550) Interface Lag in Premiere

I had to reinstall windows 10 and the problem solved.

Hi, I'm having the same problem with 4k laptop and the best soliution I've found is to make your pc screen resoliution in to 1920x1080 and use adobe products without 4k this is not perfect but i think it's the only way

I tried this hack and it worked:

Hi, I have the same problem, but I think it would not be the problem of dell, I have an ASUS NOTEBOOK with the same settings, the problem is in the 4k resolution with the dedicated video card GTX 960m 4g and the motherboard HD 530.

Hi, I have a 4K  9560 with the same issue. I bought this expensive business grade notebook for work and...  It is so annoying.

Hi, I'm having the same issue. Especially when switching to fullscreen. I can clearly see how the UI is rolling down from the top, asi if I'm loading a web page in 1995. The only solution i can think of is manualy switching the screen resolution to 1080p. It's not native resolution of the screen so everything looks a bit a blury, but Premiere definitely moves faster. Than there's this fix. You don't have to switch the resolution, but the UI of the app is still a bit blury. It moves a lot faster though. But these are just work arounds, it doesn't fix the real issue. Some feedback would be nice, it really is frustrating.

hopefully this helps.

with laptops, specifically the XPS 15, it switches between its intel 530 GPU with the GTX 960M, to utilize power consumption etc etc.

So to by pass this, and go all performance, you have to enable certain settings in your Nvidia settings. NOTE: if you go all performance, battery life will vary depending on work load.

- Locate your Nvidia Geforce Experience on the bottom right toggle menu of your tool bar.

- Open your control panel within the Geforce Experience by left clicking the icon.

- enter the 3D settings, here you are prompted with 2 tabs: "global settings" or "program settings"

     - for global, this will enable your PC to run your GTX 960M as your primary choice of GPU.

     - programming settings, gives you a control of which programs you want to open specifically to run with your GTX 960M

- for this purpose, I'm recommending you use program settings, and set which ones exactly you want to benefit from your GTX 960M for better performance, the rest can utilize the onboard intel 530 (ex: browsing the internet). This method further eliminates the XPS way of thinking, which GPU to draw performance from, and I myself have not experienced any issues with my laptop. there are some lag spikes, but I'm positive its from the lack of VRAM that the GTX 960M has to offer on laptops, which I believe is only 2GB of VRAM? don't hold me to that tho.

here are some pictures of this suggested method. hope it helps.

GPU settings: as shown - the list of "Features" is derived through the "global Settings" tab, which is defaulted to " auto-select ". Meaning it cycles between integrated GPU (the intel 530) and the GTX 960M

No luck on this fix, anybody have any updates?

Couple of people and I had the same issue before. See for reference: Interface Refresh Slow - Skylake i7- 6700hq, gtx 960m, 16gb ram, 4k Screen

Pretty much tried all those things mentioned above. Also been in contact in Dell; apparently they had their main technical team working on this but, unfortunately, didn't find a solution in the end. I believe the problem lies with the 4k screen (i'm assuming both of you have the 4k model?) and the optimization process between the GeForce dedicated graphics card and the internal graphics card; for some reason, it just doesn't render things properly. If I'm not wrong, 1080p model doesn't have this problem.   

Sadly, I doubt there's a solution atm. I've returned my XPS 15 in December and got a Dell Inspiron 15 gaming laptop (1080p), which essentially is the same machine the XPS 15 9550 but is just slightly heavier, bigger and doesn't have the beautiful yet cursed screen. Doesn't have the UI lag problem though. But still a real shame as the XPS 15 is a beautiful machine otherwise.

I have the exact same issue and can't figure it out at all. BIOS, Drivers, and Windows have been completely updated. I have a Dell XPS 9550, 960m, i7-6700HQ 2.6, 16GB ram.
