- Issue - Poor UI performance on G-SYNC enabled displays
- Adobe After Effects version number: 25.2.2
- Operating system: Windows 10 Pro 64bit, build 19045.5737
- Steps to reproduce - Open AE on a G-SYNC enabled display and drag UI bounds, then compare same action on non-G-SYNC display.
- Expected result - Normal UI speed
- Actual result - Poor UI speed
I use a dual-display setup. The displays specs are as follows:
1) NEC MultiSync® EA275UHD
2) LG 27GL83A-B 27 Inch Ultragear QHD IPS 1ms NVIDIA G-SYNC Compatible Gaming
I’ve noticed the After Effects UI performance drops significantly on the G-SYNC enabled high-refresh gaming display. This performance degradation doesn’t happen if I use the app on the NEC display. Spanning the app across both displays does not improve UI performance.
Disabling Nvidia G-Sync seems to improve performance on the LG display.
The NVIDIA control panel states “As a prerequisite for Windowed G-Sync, an application needs to be profiled by NVIDIA or manually through Manage 3D settings.”
Adding application After Effects manually via the NVIDIA Control Panel does not seem to make a difference, AE lags, still slow UI.
What is the official Adobe stance on G-Sync or equivalent gaming displays used with their software? Is this performance drop unavoidable?
