OpenGL performance worse after Vulkan update

[YOJIMBO]

After the latest update (for Vulkan), my OpenGL performance has gone into the toilet. I now get constant stutters and hiccups that I never had before. Changing to Vulkan improved performance greatly the first time I switched to it, but now crashes each time a level loads (there are already several threads about that issue).

I've updated to the latest nvidia driver and Vulkan still crashes. Would love to continue on with OpenGL as before, but it is barely playable after the patch as mentioned above. Anyone else having this issue?

i5, 8g memory, gtx 750 ti, Windows 7.

Driver is 368.69

can't use vulkan, it doesn't seem to want to install, but yes, using the same driver and on a geforce 780, windows 7 64bit, opengl doom also stutters a lot, didn't have any stuttering before the update.

OP, Vulkan will not work properly for you at this time unless you have a 4gb 750Ti - from the FAQ:

"*Vulkan is not currently supported on NVIDIA GPUs with 2 GB of RAM on Windows 7 or on the GTX 690. Users with these GPUs need to run DOOM on the OpenGL graphics API."

As to why OpenGL is causing issues, do a DDU driver wipe and install the latest drivers if you have not already done so.

Another user reported that 2GB cards will work if you have Windows 10.

Well, that's exactly what the FAQ indicates.

I have the opposite things started to fly on openGL.graphics settings raised to high.

Ya it's only 2GB Nvidia GPU's that do not work with Windows 7 according to the FAQ....

I imagine it's possible for someone to get it working but for most I think it's probably not. And I don't think they make 4GB GTX 750 ti's... I could be wrong I've seen 4GB GT 730/740's out there for some ridiculous reason.

[YOJIMBO]

Thanks for the responses. I had read Vulkan wouldn't work for my card (though oddly it did for one session). I'd just be happy to get OpenGL to work like original (still resisting the inevitable move to widows 10).

I'll try the DDU wipe as recommended by Salamand3r.

It's pretty much pointless, but they do make them.

Ahahaha. Wow. I'm surprised I never saw that before to be honest.

I'd be more surprised if you had actually even looked for it before :D

I mean, really, what is the point of the damn thing? It's logical to assume that such a card would have no reason to exist - but then again, the GTX 745 with 4GB of DDR3 is still sold on "1080p gaming" machines from Alienware, so I guess pointless products exist everywhere.

to my understanding, all of nvidia's 'lower' cards having high vram options where specifically built for SLI under DX11. If buying a single card, yes, completely pointless...but dx11 ran the cards in parallel, rather than series, so all cards had to load the entire frame buffer footprint into memory...i.e. 2+ 2GB cards only net 2GB of usable Vram. Newer api's don't do it that way...

so buying a pair of the 4GB cards let you use 4gb in SLI, also. Not quite the benefit it would seem on paper, but would allow better settings or resolution bumps in specific games that supported SLI fairly well.

That's all well and good for some of the lower end cards like a GTX 960 or possibly even a 950 I guess, but the GTX 750 ti cannot SLI...

The only thing it's good for really is in very poorly optimized games that may use more than 2GB of vram at 1080p, having 4GB would just mean that you aren't limited by vram. But having said that, at the settings that you should need to be at to use more than 2GB, the GTX 750 ti shouldn't even be getting playable framerates anyways. To me it's just a marketing gimmick.

Some people literally do buy GPU's based on the amount of vram they have. I have had huge arguments with people that literally say "but I have a 4GB card!!!" when they are confused about why they aren't getting the framerates they think they should be lol. It's tough to get some people to understand that vram is not as big a factor for lower tier cards.

Agreed. I sort of avoided the gimmicky nature of it (only pointed to it not working out the way it looks on paper), or more importantly, consumer misunderstandings of how a lot of these parts work together generally...

no different than people will laughable cpu's having 32GB of system ram...'but I have tons of memory!'...doesn't matter, the cpu will never churn through that much data faster than less memory could be refilled...but oh well.

Conversation has gone a bit off the rails haha.

I simply reverted my GeForce driver to 368.39. Not the ideal solution, but it's seemingly improved the situation after a quick 5 minute test drive.
