EDIT: Also did anyone notice on the new Nvidia drivers released today this note: "Enhanced smoothness when DLSS Frame Generation is used with V-SYNC"
Maybe this helps with Pulsar as well.
Well I think this has to do with the issues some people were facing with MFG when for example you were well exceeding 250+ FPS that the GPU utilization suddenly dropped artificially limiting the FPS to a certain value, often triggered by alt-tabbing out of the game but it often did it on its own as well while playing.
So on the PG279Q for example with 165Hz G-sync, whether V-sync was on or forced off or regardless the graphics settings, games like GTA V Enhanced would suddenly drop from 450-500 FPS and lock around ~327 fps when using 4x MFG. There was no way around this but other than disabling G-sync completely because V-sync settings were unable to aid this issue.
The funny thing was that once I lowered the monitors refreshrate to 100Hz the artificial FPS-limitation with 4x MFG started to drop to ~228 FPS instead.
I took a few screenshots back then, below is 165Hz:
100Hz:
Doesn't make sense right?
It is very vague and it was doing it without the Pulsar monitor too with just a secondary 60Hz screen.
Yet the Pulsar monitor did not exhibit these same weird FPS limit issues but it looks like some weird Hz range exceeding/G-sync combination conflicting with MFG with absurd framerates.
You can see how the frametimes went up considerably too, it caused MFG to visibly become unstable and jittery.
This has been happening since the 591.74 drivers.
Other people reported similar issues in games like Black Ops 7.
Now with DOOM TDA I could kind of reproduce it as well by limiting the monitor to 60Hz (PG279Q) and looking at the Sky in the ripatorium and it would start dropping its utilization and framerate too in situations where the Hz limit is far exceeded, no matter the settings used.
Now with the new 596.49 driver that looks solved, partially atleast.
GTA V Enhanced no longer seems to be dropping the framerate as it did before, however, when 4x MFG is active and you alt tab out and back into the game the frametimes start suddenly spiking 0.5-1 seconds or so. Once you disable and re-enable MFG ingame it is fixed until you alt tab again.
For DOOM TDA however 3x MFG seems severely broken now
On every DLSS mode from Performance to Quality and DLAA, it is extremely stuttery/jittery with all settings maxed. However DLSS Ultra Performance seems fine on both old G-sync and new Pulsar monitor.
The 2x FG mode does not seem to exhibit issues on both old G-sync and new Pulsar monitor.
Then 4x MFG is semi-smooth but it also randomly every 0.5-1 seconds the frametimes start jumping up and down from ~10ms to ~25ms so while 4x MFG before felt jittery it now just seems inconsistent, this is only on the new G-sync Pulsar monitor but the frametimes stay flat on the older G-sync PG279Q
Note that I play DOOM TDA with Transformer Model L or E for DLSS 4.5 or Ray Reconstruction, GTA V Enhanced with Preset L.
I've briefly tested the 6x MFG streamline .dll on previous drivers on DOOM TDA before but that actually made the MFG experience horrible with warping graphics in motion so those were definitely not working well on every type of title, but it does for Avatar.
But when other demanding Ray Reconstruction / Path Tracing titles with heavy DLSS modes like Cyberpunk 2077 have zero issues with 6x MFG load I don't think DLAA at 1440P should be any sweat at all for a RTX 5090, so I don't believe this to be some kind of Tensor core related utilization limit but rather software bugs.
Battleye on GTA V Enhanced is plaguing the game anyway when you go Online with 20-minutes long constant frametime stuttering a few minutes into either a full or empty lobby which transfers back over to single-player. Every lobby switch same thing. GTA V Legacy doesn't have it. People are puzzled.
Now the newest drivers I found another problem, atleast under Windows 10 22H2 Pro + ESU, when you try changing the resolution in Windows it no longer blackscreens your display, it just resizes the lower resolution image stretched to the 1440P output signal, the signal doesn't change resolution as observed in the monitors OSD and that counts for all my monitors.
Once you switch resolution in NVCP then the resolution is applied correctly and the displays go black to the new resolution signal.
Nothing, let's keep our fingers crossed that we'll have it by next week.
