XL 2546X best settings - refresh rate / fps

[MateoMateo]

I recently got the BenQ XL2546X.

Is there any point in using the Vertical Total Trick with G-Sync enabled?

Unfortunately, I have to lower the monitor's refresh rate to 144Hz, because even though my average FPS is around 180, the P95 is about 150 and 1% lows are around 85.

What do you think would be the best setup?

165Hz refresh rate + 144 FPS cap + NVIDIA G-Sync + V-Sync

240Hz refresh rate + 144 FPS cap + NVIDIA G-Sync + V-Sync (I tested this and still saw FPS drops despite G-Sync)

144Hz refresh rate + 138 FPS cap + NVIDIA G-Sync + V-Sync

144Hz refresh rate with the Vertical Total Trick + DyAc2 (I understand G-Sync would be disabled in this case)? — I’m concerned that drops might still be noticeable here

Thanks in advance for any advice!
