[WARNING] Limit your FPS now to avoid burning your hardware

xbox series S has only 10 gigs of RAM, 8 GB of which use faster bus while the remaining 2 use slower one.
I assume the goal for Asobo was to fit into 8 gigs of RAM - that is why the new algorithm aggressively unloads the objects that are not supposed to be seen. then loads other objects. then unloads another bunch.
looks like this increased rate of loading and unloading causes the mess. CPU and GPU are busy loading and unloading objects, draw more power, generate more heat, memory becomes fragmented, needs defragmentation etc. etc.

the users would have caused less trouble if they just fly straight without looking sideways


I’ve overclocked and abused ever piece of PC tech I have owned going back to a PII-300mhz unit and I have lost two pieces of equipment before they were given away or binned for new improved stuff.

An interesting debate, I was asking the same question in another thread. Whether one’s fears are rational or not, I do not like hearing my GPU fan running at max all the time, so I will be tuning graphics settings down to a point where it is at least quieter than the simulated engine noise coming from my speakers. I’ll also see if removing the sides of my PC case and simply blasting it with a desk fan allows the GPU to run at 100% without running its fan at max (cheaper to replace a desk fan than fix a GPU fan’s bearings I’d presume?).

As I understand it’s temperature that matters, not % utilisation - but whether it is possible to run at 100% GPU utilisation, but with GPU fan at 50% of max speed we will have to see.

My actual experience is that there are always exceptions.

If you purchase a computer assembled and ready to run, the power supply may be underrated if the computer you purchased is not sold as a ‘game’ machine. A game machine usually has better components and costs more as a result.

If you have built your computer from parts, then you probably already know that you should buy the next more powerful power supply for your particular system. The whole point is that there be sufficient overhead when stressed.

Cooling systems should follow a similar plan as with power supplies but my additional recommendation here is to use heat sink compound. Every thermal connection needs to be as intimate as is possible. The whole point is to transfer heat to the air.

Sooooo,
If the system is BUILT CORRECTLY it should run flat out without overheating, and it’s own internal systems should keep it from burning up.

Any PC built for high performance workloads should be stress tested thoroughly and therefore known to be stable at workloads that put their PC hardware at their limits. This verifies that power delivery is stable, and that the system cooling is working as it should.

It is absolutely normal for a modern GPU to run at 84C for extended periods. That is the designed limit in most, and the GPU is designed to throttle itself in order to make it impossible for a workload to push it beyond that limit.

The problem, is that the majority of gaming/sim PCs are not build by someone that knows to stress & stability test. Then end result is they simply load Windows and call it a day. Then along comes the user who installs their games and calls it a day.

What usually happens is that some of these builds will be problematic, even with games of today. Because they are build using a known poor quality power supply, or some other issue.

Then there are the ones that will have no issues today, but then down the road they start having issues with the newer software that pushes hardware harder than anything before.

In both of these cases, the problem can be discovered at the time of build if stress & stability testing was done, and if the tests uncover problems the builder should remediate the hardware.

This is not me just talking out of my you know what. I’ve been doing this for decades. Listen, or don’t
 it is up to ya’ll.

But if you limit FPS and find the sim is more stable, that is a hardware problem – not a sim problem. The only exception to that rule, is that apparently there have been some cases where players playing a game in early beta have had the best GPUs money can buy destroyed. And in those cases, EVGA has already put out their announcement that those cards will be replaced.

The thing is that almost every gamer out there playing demanding games does so with 98-100% GPU utilization constantly. GPUs are designed with that in mind.
MSFS doesn’t load a GPU any harder than any AAA title from the past few years – they all load them at about 100%, but the resulting framerate varies, of course.

This post is basically nonsense and really demonstrates how sheltered much of the flight simulation community is compared to other PC gamers, who are much more likely to be educated about their hardware.

When GPU is running at 100% for prolonged times, it heats up to 80C and beyond, draws a lot of power, increasing the risk of failure.

I mean, so many blanket statements here that are completely bogus. The temperature a GPU will reach at prolonged 100% load is dependent on a host of factors
 what chip it is, which specific model of that card it is since there are many different cooler designs, the airflow of the PC case and the heat output of the other components, the ambient temperature of the room
 You can’t just say “a GPU running at 100% for a prolonged period will heat up beyond 80C.” Some will. There are also water cooled cards that would hardly ever break 60C.

You also can’t make generalizations about the temperatures that are dangerous. Most modern cards are perfectly “safe” well beyond 80C, although they may start to throttle (reduce their clock speeds) to a certain extent which will reduce your performance.

Not going to bother to dissect this further because it just isn’t worth it. OP means well but ends up only spreading FUD. This post reads like somebody skimmed half an article about the issue with people’s cards frying in the beta of Amazon’s MMO The New World and understood less than half of what they read.

I have a lowly RTX 3060 and it does not get over 73C when overclocked but I get your point. It will CTD if I overclock the GPU or VRAM too much. It only gets overclocked for flight sims.

My 2080s runs at 99% constantly with MSFS, and gets to 58c. Fans at 52%

It’s also worth checking that if you have a graphics card with 2 or 3 power inputs, that you are NOT using a single cable from the power supply with a y-splitter. Eaxh output from the power supply has both power and current ratings. Just cause you have a 750watt power supply doesn’t help if you are limiting power and current by using a Y-splitter. There are 2 or 3 power inputs to the big cards for a reason.. use 2 or 3 separate cables for them :slight_smile:

I have a 5950 with a 6900xt card and I am locked at 30fps. My 6900xt runs at 95% but at 52 centigrade and my cpu runs at 10% and 45 centigrade and it is butter smooth with no popping if looking sideways and no issues at all. I am running everything on Ultra default settings.

I only have one GPU power connector (3060). It appears each additional GPU power connector is about $500+ in this market. :slight_smile:

So now with SU5, my fps is CPU limited and the GPU temp has dropped from 73C to 63C (Vsync enabled, ultra setting, 5600X).

mic drop and walks away :rofl:

I limited my fps now to 30 and the cpu and gpu both sit around 60c now.

before that they sat between 75c - 78c, probably won’t do any harm but the fans are a lot less noisy now.

The cause of the CTD may be “Exception code: 0xc0000005”

I suspect that virus checking software could be the cause, if someone want’s to play around with it.

ctd cant be related to temp, i crash even with a watercooled 3080 at 40c

as i’ve said before most ignore another probable cause - instability caused by power consumption and distribution among the components

access violation exceptions can be caused by plethora of things from simple null pointer errors, driver errors, to faulty RAM, CPU, and other components. The hardware faults may be the result of power supply instability.

we know SU5 performs aggressive unloading of the objects that are not supposed to be seen by us, and loading other objects instead. so this may lead to memory buffers mess with each other etc. etc.

I will say that I have heard of excessive frame rates damaging a video card and quite recently as well.

The Amazon funded game New World has a loading menu in 3D that lets some high end card go so bat guano on the frame rates they can in fact toast themselves. Most seem to have been super high end EVGA FTW cards so it may be a perfect storm of software and hardware?

No, whatever you have found on this is either wrong or you are misunderstanding. If you have just one cable run from your power supply with just one connector, and you are using a Y-type adapter to run that into two
 in order to correctly solve that would require a better power supply. And a proper quality power supply does not cost $500.

You can remedy your problem for around $70.

Overclocking is an entirely different discussion, if you OC you are putting your component outside of its manufacturer’s recommended specs and thus taking a risk.
