I'm having a problem where I can't quite get my 3 EVE clients to run smoothly if I have v-sync (that is, "Present interval" set to "Interval one") turned on in all of them. If I set all my clients to "Immediate", they all run at very high FPS (300+) and feel smooth as butter, but obviously this needlessly taxes my CPU/GPU and causes quite a bit of noise as the fans start spinning at higher RPMs, so I'd like to have them capped at my screen's refresh.

Unfortunately when I enable v-sync for all the clients, there seems to be some weird interaction that causes my FPS to vary wildly between 50-60 which makes the game feel very jerky and not smooth at all, even though my PC should have enough power to maintain a stable 60FPS (see specs below). Oddly enough, if I enable v-sync in *only one* client, that client does run at a perfectly stable 60FPS with the FPS monitor showing a flat line, with the other non-v-sync clients still running at 200-300FPS. Once I enable v-sync in the second and/or third client, the FPS becomes unstable and makes the game feel choppy again.

Does anyone else experience this or know a solution to this? Or maybe as a workaround, is there a way to manually limit the FPS EVE runs at to an arbitrary number? (Like say 120-200, high enough to not get annoying slow-moving tears, but low enough to not fully tax my GPU/CPU)

My PC specs are as follows:

Windows 7 64bit
Nvidia driver version 332.21 (but I've had this issue for over a year with various driver versions)
Intel Core i7 4770K / 16GB RAM / Geforce 780GTX
EVE running from SSD with fixed window mode enabled
Esharan
State War Academy

Curious, I'm assuming 1080p monitors? But with the additional resolution of 3x monitors it may be related to my post (similar FPS drops on a 1440p)

Can you do me a favor? Download GPU-Z and watch on the sensors page your MEMORY CLOCK speed, see if that throttles back at the same time you get an FPS drop.

Report back findings.

Thanks,

The resolution of my displays (I have two of them) are 1920x1200, though I think I have the same problem when running with a single display. I'll report my findings with GPU-Z this evening when I have some more time. I read your post by the way, which does sound somewhat similar, even though I've experienced this issue with even my old GTX580 and older driver versions
