To be fair, the performance delta between 32-bit builds in Quake at 320x200 doesn't seem as dramatic as that shown in the Speedtst scores. 0.74-3 gets ~212fps, 32-bit MinGW SVN build gets ~220fps, 32-bit VS build gets ~245. The VS build is about 15% faster than 0.74-3 and is 11% faster than the …

Compared to the initial tests pack, in the current 1.4 there is a change of parameters for Quake: viewsize 120 -> 100 (120 sets complete screen view, while 100 is by default, reduces the screen by the returning of health/ammo bar). This rises on ~14% the Quake's 320x200 results in DOSBox and should …

Seems, that PCem needs own benchmark theme so people could assume what computer analogue they may expect to get. For Win9x era computers, applications and games the perfrormance in Unreal + Voodoo 2 mb messured, for example. Though, newer Direct3D card emulation would be better for Win9x tasks as …

I ran this on my i9-9900KS @ 5.2 GHz and the framerate is actually LOWER (about 74 FPS) than my i7-7700K 5 GHz runs. Weird. I got 83 FPS in 800x600 in timedemo 1 in fullscreen mode, though. 2/76 = ~3% is in borders of measurement accuracy, according to what I saw. There was no significant per Hz …

Yeah it is interesting. AMD IPC compares favorably to intel processors in some benchmarks and not in others. The example where 1st Ryzens are close in the performance to Sandy Bridge (of same 4/8 and close frequency). In DOSBox 2nd Ryzens are close to Sandy Bridge, while 1st are expected to be …

Ryzen can be sensitive to memory bandwidth. DOSBox test has low influence from a memory of modern PCs. With lower or higher memory clocks you should get the same results. You may notice, the previous generation as AMD FX also has lesser performance in DOSBox than Intel CPUs of near time. In single …

Ryzen R5 3600 @ ~ 4.15ghz Thank you. The improvement per Hz is ~15% compared to Ryzen 2xxx. Now it's close in DOSBox to Intel 4xxx at the same Hz. > A note on precision boost 2.0 - it oscillates clock speed between 4.05 and 4.2ghz constantly. 4.15ghz is pretty close to the average. It's close to …

Automatically changing settings for certain games is an interesting idea. Dolphin, NVIDIA driver, PCSX2 and Windows does this for example.

There is one problem to use Ivy as retro PC. Such PC should work for longer than common.

Ivy is not significantly better in the performance, so 2600/2600k seem …

Try different software environments (and mb emulator's builds) as they may affect the emulation speed. For example, 0.74 worked faster in XP (I booted it from a Live CD, mb Alkid's one) than in Win98 SE. "soon to be upgraded to a 1Ghz Coppermine/100mhz bus" If your video card will hold 83 MHz AGP, …

It's better to ask at nvidia forum, why their software breaks official builds of DOSBox. The easiest would be to use Daum's further, where the last version I'd recommended is that.
