Hello dear blurbusters community and dear BlurBusters team, i apologize for my not so good English

i have two questions about dyac or elmb and g-sync i currently have the acer predator x25 360hz Monitor and am actually satisfied except that my image is very, very dark with g-sync i play Fortnite Competitive and play an average of 180-300fps in normal rounds and in stacked lobbies, especially in endgame, my fps drop to up to 120-150fps my question is whether G-Sync is worthwhile there or whether I am in good hands with Dyac or whether Dyac is bad with strong fps fluctuations I have also heard that you can merge G-Sync and elmb with a trick is something possible on the predator x25? Unfortunately, after hours of research, I did not find what I want to know

in short my three questions:

can I combine G-Sync and elmb on my predator x25?

is Dyac good with strong fps fluctuations?

I got my 360hz monitor for 500 € and I'm thinking about whether I should get the benq 2546K or is it not worth it?

Thanks for reading kind regards Shelful

With blur reduction you get image doubling as frame rate decreases. One thing you can do is use ULMB @144hz instead of 240 and lock your framerate to flat 144 with good limiter to get perfect fixed fps=hz sync. But this introduces classic blur reduction issues: using vsync increases latency dramatically, internal game fps limiters are not stable - screen tearing, external limiters are perfect flat but add some amount of latency too - some screen tearing too. Solution to your problems would be ULMB+G-SYNC, but X25 does not support it. Even if it did it very likely wouldn't look good. Also nvidia ULMB latency is higher compared to other manufacturers strobing implementations.

But the fact you're not sure what's the right way to utilize this tells me you possibly don't notice the difference between 240 ulmb and 360 g-sync, so why not just use what feels better to you?

That is exactly my problem that I feel it very, very strongly and first of all see what I have always heard that DyAc goes up to 60hz so I thought that it looks good up to that point I have now ordered a 240hz monitor with DyAc and will know how to test it myself you by chance whether it is worthwhile to get the viewsonic xg2431 instead of the benq xl2546k

Strobing is strobing, with dyac you'll still get image doubling if Hz≠fps. 60Hz dyac uses double strobe (double image) and you don't want that. Only thing dyac is good at is brightness. Its not that much better than your X25. I'd keep it and just choose either g-sync or ulmb.
