Bit of a GPU Melter?
I noticed the fans on my GPU were working a bit harder than usual so I took a quick peek and it seems that Retrovirus is a fairly heavy GPU user!?

In-game I could understand that - but it pushes my GPU to 99% usage ON THE MENU SCREEN - and yes, VSYNC is enabled and working (60fps) - if I disable VSYNC, the game manages about 70fps (with the odd drop) but that just canes the GPU even harder...

The fans can cope with it but I have a feeling that 99% usage on the menu is not intended behaviour? :)

I got 99% GPU usage at 47fps … This game giving my pc a work-out!

I noticed there was a comment about a recent patch introducing some GPU-related issues - but I'm assuming they've patched again because the file they suggested removing doesn't seem to exist anymore...

I'm still a bit wary of playing a game which is trying to melt my hardware tho - even if I reduce the resolution (from 1920x1080), disable FSAA etc. it doesn't help that much - GPU usage remains 75%+ - even in the menus.

Something is amiss I think...

p.s. W7-64bit - 650 Ti Boost 2Gb - latest drivers AFAIK

Digging around - I guess this is the same issue

Sounds like.

And, like I wrote in that other thread, it isn't an issue at all as long as your case is clean of dust and you have good ventilation for your system. GPUs are designed to run at that usage level.

Oh it's most definately an issue - 100% CPU usage IN THE MENU is a bug for sure.

In-game GPU usage is higher than I'd expect but it varies depending on what's going-on - but it simply maxes-out in the menu which is idiotic (given that people may leave the game in the menu for LONG periods).

I've built this PC around quietness over performance - this is the ONLY game I've played in months which has pushed fan rates to the point of being audible - games like NFS: MW2 and Batman: AC don't even do that!!

Clearly something is asmiss - and it's not the usual VSYNC (stupid FPS) issue for once.

Two things.

1. When I said "it isn't an issue", I was referring to the GPU running at ~99%. And, I still say that isn't an issue, because they're designed to do that. You not liking the noise is a different matter. In the future, buy a GPU with lower fan noise at peak rates (something with larger than normal fans).

2. ~99% GPU usage in Retrovirus's main menu isn't surprising at all, because that menu is a fully rendered scene just like with the Total War games (TW: Shogun 2 in particular). In Retrovirus, it's a largely static scene, so nothing in the system is going to be the bottleneck besides the GPU. So, if the engine is optimized for your system properly, you should be getting nearly 100% usage from your GPU with VSync Off.

If the scene was pre-rendered and didn't use the GPU or if the scene was frame-rate capped at 30 FPS (like in Sanctum 2), then a lower GPU usage would be expected. But, that isn't the case. Your GPU is giving you the full loveliness that scene can provide. In other words, completely correct and expected behavior based upon the small amount of data you've provided.

So the fact that in some people's PCs are going to overheat and shutoff isn't an issue to your eyes then? 8)

No GPU is designed to run at 100% for long periods because no application would ever ask them to do that - things like Furmark were created to test what happens IF you do that on a hypothetical basis - a worse-case scenario.

End of the day it just makes me wary of playing the game - I'm pretty sure my PC would stay cool enough but I also get the feeling that this sort of thing is just shortening it's life for no particularly good reason.

Even if we accept your assertion that it's "expected" - a menu which could cause a PC to hit it's thermal shutdown is a bloody stupid menu.

You're not talking about a thermal shutdown.

And, yes, there are a lot of video games out there which run people's single GPUs at near 100% for long durations. That's why I run an SLI system, so my usage usually stays between 50-80%. That's also one reason some games (such as Borderlands 2) come with frame-rate limiters.

For instance, I ran Retrovirus safely for over 19 hours without breaking anything on one GPU.
Migz - DH Oct 12, 2013 @ 2:10pm 
You bringing up Furmark brings up an old thought of mine.

What is more intensive for a GPU? A program like Furmark which forces the GPU to render thousands of single elements at low FPS? Or a simple scene rendered at very high FPS?

If in both situations the GPU says it's running at 100% usage, are they really the same? Or is one worse? I don't know. It's a technical nuance I'm unfamiliar with.

But, anyways, in the end, what you do or do not do with your equipment is up to you. If you don't feel comfortable playing Retrovirus for fear of burning out your GPU, ok. But, I think you're needlessly skipping an interesting game.

What bothers me is the choppy performance. 99% usage, OK, but even lightin set to low, no Vsync (adaptive throguh control panel) and no AA the game feels horrible I can run BioShock Infinite better then this. And it's not like TRON games, looks good, but not that good.

I reckon if I left my PC for 3-4 weeks without clearing the fans/heatsinks (as many people probably do) and then left this on the menu it would eventually push temps into auto-shutdown territory.

It pushes my GPU's temp up at the same sort of rate as Furmark - within 1-2 mins it's as high as it ever gets (high 70s) - 1-2 mins after that you see case temp start to rise - 1-2 mins after that CPU temps start to creep up and so the GPU, CPU, Case and even PSU fans all start to speed-up - maybe it would be OK - maybe, not really keen to try it.

I could, of course, use more cooling but if I wanted a helicopter in my office I'd just get an XBOX 360 :)

If it was in-game that would be one thing - and I'm going to re-iterate this again - but it's IN THE MENU!!

Pretty much as harbinger-hu said - you have to wonder WTF it's actually doing - and I'm rather disappointed that the developers haven't picked-up on this or the other post...
Migz - DH Oct 12, 2013 @ 6:05pm 
70s C for a GPU at high usage is really good, actually. In the summer, mine can creep up to 82-ish, but my normal operating temp is between 56-72C.

The burnout points for most GPUs is around 100C.

I think the heat-soak from the GPU would probably tip something else before the GPU hit 100 - it's the peril of running a 'low noise' PC, we use minimal fans and rely on passive heat distribution - but a GPU being pushed close to 80 degrees and staying there (no other game I have does this) needs active cooling to counter-it.

When I was testing this I actually took the side of the case off to check there was no dust and the WAVE of heat coming from the GPU was really something - the cooler works but it's not brilliant at directing the hot air out the back, most of it rises from the cooler and ends-up inside the case :(
