You might get some improvement from the GTX 1050 (Ti) GPU, mainly due to its greater amount of graphics RAM. Your current R7 250 is a lousy GPU to begin with, being a lower-end derivative of an architecture that dates back six years (all the way back to 2011). And with only 1GB of onboard graphics RAM, it simply isn't enough to handle 4K smoothly if at all.
Thanks for you reply. I'm sure I might get 'some improvement', but I'd like to hear from some GTX 1050 owners as well how it will performe because I am looking for some more sureness before buying :-)
What really is holding you back is the fact that while you have an i6 8600K 6-core CPU it is not hyperthreadable so you have less CPU power than a hyperthreadable 4-core CPU.
What is your storage system?
What format is your media?
GPU Acceleration is only usable with some features and effects
Using a Samsung 850 EVO 250GB SSD for OS (Windows 10) and Premiere Pro 2018. Media is from my Mavic Pro drone stored on a traditional HDD.
Mainly using color grading (manually or using LUTs) and speed/time remapping. I suppose that I should be able to view my timeline smooth when adding a GPU? But...:
"The Core i5 8600K also did fairly and only fell behind a bit with 4K RED footage that included Lumetri Color Correction and cross dissolves. Even then, the fact that it can play that kind of project at half resolution without dropping any frames is pretty good."
This should mean I do not need any GPU for live playback my timeline with Color Correction and cross dissolves... I'm lost now :-)
I'm not sure why, but I concluded that the test took place without a seperate GPU but it looks like they used a GTX 1080 ti.
Any users here using a GTX 1050 ti in Premiere Pro? How is the live playback of your timeline with effects and color grading adjustments?
