FPS Spikes

What about an m2 NVME SSD? Wouldn't that also help? I have Western Digital SN850X at 7300/7000 read/write mbps. It can't even reach its full potential given how none of my slots are 4th generation, only 3rd.

The GPU and CPU combo going to be a limiter still.

Not really. From experience, Trainz does a lot of reading at load time but not a lot while running your route. You can see this if you bring up Task Manager and then click on the performance tab then your hard disk.

Watch the graphs and the numbers at the bottom.

What I noticed on my system is a huge write cycle being done when content is being validated. I also noticed that SP5 does a lot of validating and this constant asset validating causes a big performance hit. How to get past this is another issue altogether. I tried precaching content and that didn't help.

There a lot of things that will help.....the question is how much better will I be after? The GPU is going to give you the biggest bang for the money. Start there.

Agreed but you need a decent power supply and lots of cooling as well. Then it's wack a mole, which bit becomes the new bottleneck.

I'm not even sure just selecting the right content would be better. I ran some comparative tests on an RTX 2070, an RTX 4000 and a RTX 3080 all gave reasonable 30 fps frame rates but the GPU usage rate was slightly different but not by a great amount.

For anyone that owns a 40's series nvidia card, You can you dlss with unsupported games now. In trainz, i can get 200fps with it on. Smooth motion doesn't work though. Trainz won't even launch with smooth motion turned on. Just a suggestion for people with the 40 series cards. This might improve performance for some. If i lock the framerate to my monitors refresh rate, Mine stays capped at 75 fps.

Can you advise what your DLSS settings are?

He has a 600 watt PSU now....that should be fine. Extra cooling will probably help only if the GPU gets too hot. I have an RTX 2070, 3070, and 4080 12G. I like to run with it locked at 60 FPS. The 2070 cannot do this. The 3070 will, but creates blast furnace type heat. The 4080 doesn't whimper at all and the temp stays about 48*C.

I can't imagine how hard that 4G GPU of his is working.

A faster NVME is a waste of money and will not speed up Trainz. I mentioned this in another thread a month or so ago.

Here's the same question asked on Tom's Hardware forums.

A faster GPU is your best bet, but you need to ensure that your CPU can keep up with the new GPU, otherwise there will be a bottleneck.

Based on what I'm seeing the worst buffer and index count is that fence. Now there may be other problems yet to be discovered but the fence clearly is causing some sort of trouble.

This is in surveyor mode. I'll do this in driver mode too.

Getting a faster NVME isn't a waste of money. It does help in some major regards. Particularly when it comes to downloading items off the DLS, Trainz Store or even installing TRS22 itself. It does also load up much quicker than on my old computer with a SATA SSD. For those who purchased Trainz through steam, the amount of time to download the 13GB base game is much faster on NVME SSD Drives. It could take up to an hour maybe longer depending on internet bandwidth when using SATA SSD.

No one is arguing about the NVME......but looking at his system, the weak link right now is that GPU.....it is too slow and little RAM to go along with the speed. If you were to pick the ONE thing that will give him the biggest bang for the buck, it would be a new GPU.

Download speed is bound by your network and not your hard disks. The actual installation will be faster due to the fast read speeds.

I have Xfinity high speed cable and I have spinning rust and it doesn't take that long to download and install content. I do use enterprise-quality Iron Wolf drives that may make a difference with the large caches but they are not as fast as SSDs, and I keep the hard disks defragmented. I use these because the cost of 8TB SSDs was $849 each versus $250 each at time and they still cost that now.

Let's say someone has less than Gig-speed internet, maybe half.
Having an SSD faster than that will not make the downloads any faster.
Data transfer between folders and install after a download will be quicker but not download speed.
As time goes on, faster ISP options are available.
If you were lucky enough to have fiber internet speeds at 2.5Gig or faster download speed, then a faster SSD will reveal a benefit to download speeds.
I'd agree the money would be better spent on a higher performance GPU first.

Absolutely!

Then there is matching the disk controller to ensure that the maximum throughput is available for the storage devices. A PCI-e device is ideal but then there's the issue of the buss being bottlenecked due to other PCI-e devices or an underpowered CPU.

I agree, a better GPU is better investment at least for now.
