Annoying Stutters when tile loading getting worse.

[johnrossetti]

Bare with me on this one please.
18 Mths ago I pushed the boat out and got myself a fast PC.
X299 Pro gaming motherboard, i7-7820X, GTX1080Ti,32Gb DDR4-3000MHz, NVMe SSD, etc, etc.
When I got the PC I’m pretty sure I was running TS2017 maybe 18. I came from a PC running W7 on a Pentium 4 and the improvements from the new PC were significant (mainly in frame rates) (I'm running the same VDU’s now as then 1280x1024) I didn’t see much of an increase in picture quality but with the new PC I was able to up all the settings almost to Max and the frame rates were still in the 100’s (even on WCML North)

Since then we are now on TS2019 64bit, Window 10P has had many updates and so have the Intel CPU’s (Spectre etc.)
The Point of this post…is….over a period of time, in the back of my mind, I am sure I am noticing more freezes when the next tile in the scenery loads. Picture quality is the same as are the frame rates but the Jerks/Pauses/Freezes are getting very noticeable. Could it be TS2019 or even W10/Nvidia Updates ??
Anyone else had similar thoughts ? or better still evidence.
Just for the record, when I got the PC the figures from a Passmark Test were for comparison to now

No hardware has been changed in the time I’ve had the PC and the drives have plenty of space left .
Cheers John

Are you sure you don't mean you're running at 1920x1080 as a GPU that high is overkill for that resolution?

Also the main thing causing tile stutters would be SSD wise, that passmark test shows it degrading by quite a bit.

[johnrossetti]

Agreed re card I really am running at that low resolution as I intended, still do,to get a 4K VDU looked at some last year, not impressed but like the Dell P4317Q 3840x2160 because of it's PIP (4 split screens)

Yes but I dont see how the M.2 SSD can "slow" down except I forgot that I only had 2 at first now have 3 but I was assured that would make no difference unlike SATA which may slow slightly.

Hi, there seems to be a bit of a general slowdown - are the case and all of the fans/heatsinks clean?

[gptech]

A;l drives will *slow down* as we put more data on them. Don't forget that even SSDs get fragmented as it's by product of the file system. With an SSD it doesn't particularly matter in real world use, as the speed of them makes any pauses imperceptible. An SSD will never eliminate completely tile loading stutter, and it's only accepted that the most probable cause is the data transfer time from disc to RAM. There may be several other contributing factors that have never been identified.
Don't get too hung up on benchmark figures, the results between then and now show the PC still in the higher percentiles for each tested component.

I am sure I am noticing more freezes when the next tile in the scenery loads.

But are you running the exact same scenarios on the exact same routes with the exact same rolling stock?
Stick a heavily scripted loco on a big route with lots of AI and you'll see differing loading induced/related effects.
What other software do you have running in the background?

[johnrossetti]

Thanks for ideas all. Now doing tests on both pc's to see whats afoot (12")

look if your SSD needs defraging.did mine for that reason and that stopped the sut sut sutters.

I was under the impression that you should not defrag a SSD card as it is not required. Is this correct or not?.

Under Win 10 you shouldn't need to do anything to any drive--regarrdless of which technology. Defragmenting, or Optimising as it's now called under Win 10, should run (if needed) as part of Windows' bacground tasks.
There's nothing wrong with running the routine to check the drive's condition of course, and if you do opt to run it it won't defrag your SSD in the old manner. It essentially just runs the TRIM routine. If you optimise a spinning drive Windows will do it the old fashioned way.
All drives become fragmented, thats how file systems work, but this fragmentation is only caused by writing to disc---simply pĺaying TS will not fragment the files a route loads. If optimising a drive improves things it's more likely to be because Windows isn't navigating through a load of old redundant files rather than any change to the game. That suggests that there's more at play...was the drive too full? do both Windows and TS live on it?
