Thanks for looking into this.I'm not good with computers, but here are my findings:
1) Nvidia GTX970M
2) Resolution pre and post patch: 1280 x 720.
Graphical settings pre and post patch: Standard (Laptop) settings. Frame rate pre patch: consistent and smooth 60 fps when the frame rate limit was set to 60 fps (refresh rate 1/1). When disbling the limit, the fps stayed between 100-120 fps.
Frame rate post patch: 60 fps with the frame rate limit set to 60 fps, but with several drops per minute to 40-50 fps. (The game appears to freeze briefly.) When disabling the frame rate limit, the fps stayed between 100-120 fps as before, but with drops to around 90 fps several times per minute. (The game freezes briefly here as well.)
3) When I limit my fps to 60, the GPU utilization is between 50-70% (see left side of the below screencap). When I remove the limit, it's at 100% regardless of which zone I'm in (see right side of the below screencap).
The above screencap was taken when I was in my character's apartment without moving. Here is another screencap that I took during a fight (set to 60 fps), where the GPU utilization seems to spike (?) before dropping:
4) The spikes occur in every/any in-game area.
5) This is not accompanied by any graphical glitches. Aside from the stutters, the game runs very smoothly. However, if I use a spell or skill at the same time as a stutter happens, the skill/spell won't register and I'll have to use it again.
6) Everything I've tried to alleviate the issue:
- Cleaning the fans of my computer (the avg. temperature is under 50 degrees celcius now, and when the GPU utilization reaches 100% the max temperature is 64 degrees celcius.
- Checking all drivers and all Windows Updates (everything is up to date).
- Changing settings related to FFXIV in NVIDIA Control Panel.
- Overclocking the graphics card.
- Restarting the game and the computer.
- Shutting down other apps and programs (and game mode).
- Switched between DirctX9 and DirectX11 at game startup (the problem persisted in both).
- Changed the frame rate limit in-game between 15 fps to 120 fps (the fps still dropped/skipped many times per minute, whether the fps was high or low).
- Changed the graphics settings from lowest to highest, and back to lowest.
- Tried Windowed mode, Borderless Windowed mode, and Full Screen mode (the problem persisted in all three modes).
- In the FFXIV Launcher under Settings, I tried to reset the system settings.
- I freed up some space on the SSD where FFXIV is installed.
None of the above helped prevent/remove the stuttering. I feel that I need to underline that the game runs very smoothly all the time (or has, until now), but after the patch, these "skips" interrupt the otherwise smooth gameplay many times a minute. If I click something right at the same time as one of these "skips" happen, the button I click won't register, and I have to click it again.
Sorry if I included too much (or did I maybe miss something?).
