Ex-NVIDIA Driver Developer on Why Every Triple-A Game Ships Broken & Multi-GPUs

I'm genuinely interested in this subject, yet I won't go to this website. They have spent their credibility long ago.

Don't mention it

We’ve all known that most triple-A games release broken on the PC, however it’s good witnessing a former NVIDIA dev publicly acknowledging this while at the same time revealing some new ‘inside’ information about what’s happening with those ‘Game-Ready’ drivers we’ve been getting when really big games come out.

GameDev’s forum member ‘Promit‘ (who was an ex-NVIDIA driver developer) claimed that nearly every triple-A game ships broken (or at least shipped broken when he was working for the green team):

“Nearly every game ships broken. We’re talking major AAA titles from vendors who are everyday names in the industry. In some cases, we’re talking about blatant violations of API rules – one D3D9 game never even called BeginFrame/EndFrame. Some are mistakes or oversights – one shipped bad shaders that heavily impacted performance on NV drivers. These things were day to day occurrences that went into a bug tracker. Then somebody would go in, find out what the game screwed up, and patch the driver to deal with it. There are lots of optional patches already in the driver that are simply toggled on or off as per-game settings, and then hacks that are more specific to games – up to and including total replacement of the shipping shaders with custom versions by the driver team. Ever wondered why nearly every major game release is accompanied by a matching driver release from AMD and/or NVIDIA? There you go.”

Promit shared his opinion about a lot of topics, and talked a bit about multi-GPUs. As NVIDIA’s former developer said, multi-GPUs are f’ing complicated.

“You cannot begin to conceive of the number of failure cases that are involved until you see them in person. I suspect that more than half of the total software effort within the IHVs is dedicated strictly to making multi-GPU setups work with existing games. (And I don’t even know what the hardware side looks like.) If you’ve ever tried to independently build an app that uses multi GPU – especially if, god help you, you tried to do it in OpenGL – you may have discovered this insane rabbit hole. There is ONE fast path, and it’s the narrowest path of all.”

Promit concluded that these issues will be mostly addressed by the new APIs. The new APIs, Promit said, are the right step, and they’re retroactively useful to old hardware.

It remains to be seen whether developers will be able to code properly for these new APIs!

Go to the source itself on the GameDev.net forums:

If you're interested in the subject you may want to read the whole thread in context too then.

I'm definitely dumping my SLI setup and going single card. Probably getting the Kingpin.

ShottyGibs1852d ago

I use SLI, if you learn how to use Nvidia Inspector you can get all games running well with SLI way before official drivers come out. I love SLI.

Grave1852d ago (Edited 1852d ago )

I've been using SLI for years and am very familiar with Inspector and it has helped. I am just tired of almost every release being a troubleshooting session before I can get it to run properly. And if I don't I'm stuck waiting for a proper SLI profile. I'm done with it.

So we are paying $60 for sloppy coded pc games and gpu vendors have to do all the work to make the games run decent, free of charge.

no wonder PC is so easy to develop for, they don't bother optimizing anything, somebody else will do it for you. When people complain on your tech support forums you bide time till Nvidia fixes it for you.

Real classy guys.

I've actually got PC buddies who are selling their setups and getting PS4s because they're sick and tired of this crap on PC.

traumadisaster1852d ago

Then they have old hardware they don't want to upgrade.

Poor game performance is frustrating and a capable card and cpu is required to not have problems.

Out of 400 pc games only a few had issues.

I actually switched from consoles to PC right before this gen started. Mainly due to the fact I could finally afford it.

With the state of affairs in gaming today. It's really annoying to see how consoles have benefits to some folks even after (personally) dishing out over 2.5k for my first build ever. This is considerably more than consoles. Really odd to see how you can pay so much yet still feel robbed in a certain way with the garbage some of these developers are putting out. Then again this PC has replaced all tech in my home (I still got the PS3 and tv with cable etc..) aside from my cell phone.

For those wondering:

i7 4790k
Nvidia gtx 980
GSkill TridentX 2x 8gb at 2133mhz
128gb m.2 storage from plextor
250gb Samsung 850 Evo SSD
