Just a F.Y.I for those using Looking Glass and getting less fps then what your in-game fps displays. There is a way to remedy that but at a performance hit.
RTSS had a new feature implemented awhile back which was designed to emulate a V-sync on experience while having V-Sync off. It was called Scanline Sync. We don’t particular care about that, but they did implement a way to flush GPU buffers while putting in the feature. Doing so prevents the guest GPU from utilizing itself to 100%. This leaves room for the capture API to do it’s thing, and send frames to our host GPU.
All that needs to be done is to create a profile for your preferred game, for this example DOOM, and set Scanline Sync to any number.
Once your profile is created, go to the RTSS config file that was just created for your game and add
SyncFlush=2 under the
Once done start up your game and check out the difference. Changes can be done on the fly by flipping Scanline Sync to 0 in RTSS to measure ‘on’ and ‘off’ performance. Check out the UPS differences below.
This has worked for every game I’ve tried, at a cost of around 10 fps, and 20-ish if you’re already pushing the the triple digit ranges. You can even full screen now to reduce input latency even more. Unfortunately, for those wanting to hit triple digit frame rates, you’re going to need some serious hardware to push that while flushing the GPU.
Doing this all has made me realize I really need a new graphics card. Anyway, you should be able to ‘see’ all the frames now. I’ve been running this for a few months and never bothered to make a post about it. Figured I’d get around to it sometime.
Just thought I’d get the message out. If anyone has a 1080ti/Vega or above, I’d really like to see how it works for you!
