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.
