Slowdown on extended play time

[SegaLover2020]

I'm using one of the latest builds and I've noticed that after a hour or so the game that's currently playing starts to run slower.

It's like the virtual machine has some memory leak or can't run properly affecting the frame rate and screen updates. I've tried changing processor speeds, graphics settings etc but the only fix is to exit and reboot supermodel. On restart, everything's fine and smooth for about 45 minutes.

I'm using an i7 7700hq laptop with 16GB RAM and a GTX1050/intel 630 graphics card. No temps issues or overclocking active, I run a few benchmarks and the cpu/gpu reach 30% use max.

Anybody has more info or a solution?

Me too, same exact problem here!

• r803 (x86_64)
• srally2
• Win10 PRO x86_64
• Intel i3 4130T
• Intel iGPU HD Graphics 4400 (ver.: 20.19.15.5144]
• 4GB RAM

Did you try force using nVIDIA only? Also, are you having this issue on what OS?

What do you mean? Can you give us precise frame rate figures over time? I think this is thermal throttling. Supermodel is continuously using 30% of your CPU, which means one of your four cores is under constant 100% load.

Nah, multithreading works very well and all 8 cores are active at the same time. I monitor everything with msi afterburner and my temps are lower 60c with supermodel. Frame rates are 55-60 with either gpu (resolution is the bottleneck) but after some time they drop to 30-40.

Windows10 version 2004.
Both cards work about the same, only difference is intel graphics can't go higher than 720p and mantain good performance. But that resolution is more than enough for me anyway.

Me too. Thermal throttling is not the problem.

Will you manage to try on Linux (and/or macOS?) I was wondering, could be somewhat related to some internal obscure "bug" deep inside Supermodel code?

I ran it for an hour and noticed no such behavior. Memory usage went from 380-406MB, so it doesn’t seem there is any memory leak (we don’t do any allocations that I’m aware of anyway).

I'm trying to narrow down the problem, so far the game that suffers the most is virtua striker 2. Doesn't matter which version or graphics setting, after about half a hour it stutters or slows down (depending of vsync or not). This is happening on the latest SVN as of 27 september 2020.
