I'm just curious as on my PC Intel i5 10600K CPU and an Asus RTX3060 TI GPU my GPU is used quite a bit more than my CPU. To find out on Windows 10 or 11 you can monitor this from the Xbox game bar. To bring this up press the Windows key + G and click on performance. I am asking this because of AP's statement on their MML route as I have read that TSC2024 users your GPU more than your CPU. RAM: 8GB Processor (CPU): Max turbo clock rate 5GHz Graphics card (GPU): Train Simulator Classic is very heavy in its use of your processor so your graphics card isn’t usually so important. Anything remotely well matched to your processor so your graphics card does not cause a bottleneck will suffice. You can find out whether your graphics card is a bottleneck by reducing the resolution you play at. If your FPS increases when reducing the resolution, your graphics card is probably what is limiting FPS. This enhancement pack will still function just fine for those with lesser systems than what is recommended above, but FPS could well be limited in the aforementioned busy/detailed areas
In my case it's 5-10% CPU and 75% GPU. However my CPU has 16 cores, thus 6.25% is the single thread cap, which I roughly got, until I installed the gaming software which shifts a bit of work back to the CPU. (Other stuff, like the performance monitor itself is running, too.) Most games are GPU heavy. The most extreme I measured was 25% + 50%. I think TSC is both CPU and GPU bottlenecked - heat management core shuffling aside it very much appears to be single thread (at least in terms of the heavy duty, which was also explained by Steve) while its drawing style requires a serious GPU (doing large amounts of simple operations, such as drawing hundreds of 2D trees and cardboard houses). Quite possibly it's not even necessary to have anything beyond an entry level CPU. Except it may lack bus speeds or certain instructions. But in my case, a casual Dual Core (2004?) would do
Thats very interesting cpu usage has seemingly changed to when I looked at it extensively in TS2016! CPU, RAM USAGE TS 2016 with i5 4670K at 4.2GHz, RAM 16GB, GPU GTX 970 3 scenarios - 1 at night, 1 x sunny, 1 x rainy, Measured with hardware Pertelian Process Lasso installed optimising cpu usage NOTES: · No significant difference overall between CS, STD, DD, FR scenarios. · The figures were taken after the scenario has loaded and you were ready to start the scenario. · Based on 3 scenarios, Season - Clear, Rain/Snow & Night · AI usually made only 2-3% difference if any, but in some extreme cases a 30% difference in cpu usage seen · RAM usage stayed very stable changing only by 1% when scenario fully loaded. · TS 2016 frame rates capped at 30 fps using “Launch Options” via Steam. · Frame rates were mostly stable with few changes in the scenario (except at known tile boundaries). · Fluctuating frame rates are associated with stuttering. · CPU usage changes at tile boundaries causing the biggest fluctuation in frame rates. · Train speed no significant difference in performance · Some smoke from steam engines affected performance · Some buildings non-specific affected frame rates significantly circa 30% (Same with some bridges) · Type of loco did not affect performance significantly, except new Class 390 Pendolino (with AI in scenarios) · Tile boundaries caused significant temporary drop in frame rates, usually accompanied by a cpu usage change both up and down. · A drop in frame rates usually meant an increase in cpu usage – but NOT always. Several other roues tested but not shown here. GPU usage not measured.
"Some buildings non-specific affected frame rates significantly circa 30% (Same with some bridges)" Ooh you tease!
