TS2021 reduced to a crawl

[mojo12012]

Tea break over I had another go at a fix. I decided to use Cobraone's raildriver programme. I then started TS 2020 64 exe and got the following message:
Programme mismatch
This programme (Raildriver) is running in 64 bit and TS 2020 is running in 32 bit. You need to exit and start 32 bit version (of Raildriver). A few seconds later I got a message telling me to log into Steam, which I had forgotten to do. Is it possible that I am running the 32 bit version, even though I click on 64 exe?? I have reseated card, memory, and power leads. The same issue: if I turn on dynamic lighting then fps drops to 14+. Turn it off and it goes to 50-60 fps+. Verticals continue to shimmer. At least they shimmer better on the bigger screen

[mojo12012]

The new monitor with its higher settings have made some difference to the shimmer and wavy verticals and horizontals. Setting the fps to 30 gives a very smooth ride with no noticeable stutter. If you're not moving then it's a great view from the cab!

Try the game without the raildriver.

Hi Gary. I found during the testing regime that having Raildriver on or off made no difference to the programme. I have found that my monitor supports AMD's Freesync. Although my gpu is Nvidia apparently using the display port allows the two technologies to work together. Maybe a possible workaround. Now waiting for the cable. Will continue experimenting. Cheers.

Not really anything to with DP except it has much better bandwidth than HDMI (later versions may have caught up)- nVidia updated the driver software to work with many newer FreeSync monitors. aka Gsync compatible.
Have you set the monitor as G-Sync compatible in the NVCP.
Setting a fps limit for a freesync/gsync monitor is IMO counterproductive.
They display any frame sent from the cpu to the gpu immediately (unlike conventional monitors) so setting a fps limit of say 30 and the freesync monitor wants to display an image sent at 60 fps - means that in effect the monitor is throttled.
Also setting AF and AA settings in the NVCP as 'application' controlled and not 'enhanced' means that you are not using the power of the video card to render images in TS, ie using TS only. Have a look at my guide on UKTS wrt to setting up TS with a GSync/Freesync monitor - you might be some tips there you can use.
Looks like you are getting there! UKTS File ID: 39460

Thanks for the further tech insights, Peter. A whole new way of looking at things literally!

[mojo12012]

So the problems continue. Followed ph's settings to the letter. TS running like a photo frame! Used Unigine's heaven benchmark to see what that was showing. Beautiful picture, no tearing or shimmering, but then there wouldn't be at 3-5 fps!! So it's not TS or settings, and starting to look like it's the gpu. Thought I'd try a Win 10 reinstall. Couldn't reinstall or repair-says the ssd is corrupted, so I've obtained a new ssd and will reinstall on that. This whole graphics' issue predated the win 10 installation so this seems to be just a separate glitch. Am I missing something in the bios? That's about the only thing left to consider after the reinstallation. If I get another equivalent gpu or better then the next birthday and Christmas presents may already be accounted for

It could also be the CPU or the RAM - have you tested tose.

[mojo12012]

Peter. How do you test cpu and ram? Gpu seems well covered. Memtet showed no issues. Win 7 works perfectly, except with TS, when I reconnect the ssd. I'll do the reinstall and see what happens. Power supply seems okay. It's a Corsair 1000 watt, and never gets warm. I've resited the ram in the prescribed alternative slots without any change. At the moment the pc is in bits while I install the new ssd and take the opportunity to reroute the cabling and check all the connections again. Certainly making the grey matter work!

Sounds like you have all the bases covered memtest is good and your cpu seems OK too.
The OSes, 7 and 10 - seem fine.
No temp issues with the CPU under load, ie running TS? Old thermal paste - long shot!
This is a strange one with no easy solution.

What CPU and GPU usage is reported while running TS, or a benchmark, or anything which exhibits this low framerate? Might give a clue as to where the fault lies.

[jstange]

I already said several pages back it seemed to be a GPU issue and suggested installing gpu-z and running it together with a furmark test to see what the GPU was doing, but I was totally ignored. I've stopped posting here since then (ok, this post is an exception )

During furmark GPU reports 200% TDP while producing very low fps and has 28 deg. Celsius (which means it's doing nothing while being over its TDP - very weird).

Looking for old thermal pastes is ridiculous...

[mojo12012]

Well it looks like the graphics card after all! Reinstalled cables, one component at a time, after stripping everything out, and rewiring. When it came to the gpu the psu refused to boot, although power was being provided. Each time I disconnected the card the system booted. When I reconnected the gpu the psu would only click, although the led on the card indicated there was power. I used the paper clip trick and checked all the power outputs. Everything was spot on. It appears the card must have been failing over time. The puzzle was why it seemed to be working in other applications e.g. films etc. Sorry jstange if you felt you'd been ignored. Deep down I was hoping by looking at everything else first, it wouldn't mean a new card. Not at today's prices anyway. So, unless anyone can indicate another, fixable reason why the card should short out the psu then it looks like a prolonged internet trawl to find an equivalent. Not been able to find a new 1070 anywhere. Does anyone have a suggestion as to what level of card I should be looking at, given I am not a serious gamer, but would like some future proofing, as well as getting my fps back on Trainsim?
Thanks for all your help.
Cheers.

I am really sorry that you find my suggestion wrt thermal paste as being ridiculous. I did say long shot!!
That is not the sort of remark that I would like to see on this forum - it was in poor taste.
Perhaps the moderators could consider removing it! In the context of what I suggested it is totally unwarranted.

At the time I recommended looking at the cpu/ - mojo wasn't sure that it was his card as he states it even runs films OK

The puzzle was why it seemed to be working in other applications e.g. films etc.

That doesn't sound like a failing video card. You even said:

In my view we certainly do not need to dig deeper into TS settings, it's a system wide graphics performance issue.

How could it be system-wide when it works with some applications, and apparently only TS was affected?

Sorry, but I do NOT place much faith in artificial benchmarks they usually do not reflect what is happening in real-time applications. I prefer to look at what could be happening in a physical sense.

Now in the latest post from Mojo we now have a video card that is apparently shorting out the psu - how is a gpu benchmark going to tell you that when the PC won't even fire up with the card in place? If it was my card I would be looking at all of the pins on the card - and the mobo - even trying it in a different PCIe slot if there is a second one.

but I was totally ignored.

Ignored to the extent of mojo actually running the test and posting the results in here?...

I love this sort of collaborative trouble shooting......
