I realized I never benchmarked my new PC (i5-7600), so I set about doing that now. And decided to do it on my terminal, because why not? Here are the results. http://www.zerker.ca/misc/forumstuff/DSC01672_thumb.jpg http://www.zerker.ca/misc/forumstuff/DSC01675_thumb.jpg FYI: Debian Stretch and …

So I did some additional testing and wasn't able to make it work either, even on an SVN build, despite finding some clear advice to indicate my previous config suggestion was correct. That said, that particular page doesn't give very good advice on the Linux side; on any Debian-based machine you …

This is a rather confusing request. FT232RL is a USB to serial converter, so what "program" are you trying to run? What is your intended goal here? What are you connecting to the other end of the FT232RL? Are you using a null modem or straight cable? In DosBox, you should be able to set the serial …

It takes a bit more than a single typo to destroy your hard drive in this particular case. You'd actually need to explicitly specify the hard drive device as an output file.

For *nix users, you can easily use dd: $ dd if=/dev/cdrom bs=1 skip=33581 count=8 199307028+0 records in Just note that the 8+0 part is not part of the data. In this case, the date is 1993-07-02 Or for the full header: $ dd if=/dev/cdrom bs=1 skip=32768 count=882 Honestly, I don't think this thread …

So I got the numbers with the u7dcp patch and l1 cache disabled: 148.4 seconds for 10 round drips, or estimated fps of 7.5. I think the ACPI speed throttle is a much better solution for my PC.

I can give it a go, but I suspect for my PC that disabling cache would make it TOO slow. I recently benchmarked my machine for clueless's cache disable thread , and found a 1/8 speed throttle (which was ~20 fps for Ultima 7) got me a Doom timedemo framerate of 12.90 fps. Disabling level 1 cache got …

So I added some entries to this list. I also wanted to benchmark the effects of CPU throttling. I used fdapm for this, but throttle has the same effect. I wasn't sure how you would want this sort of thing marked; I just put a extra artificial multiplier on the clock speed column. I'm pretty happy …

Stock setting is pretty similar to the original post in this thread ~205 FPS and way too fast. FDAPM SPEED1 results …

It's a later SVGA card (Voodoo 3), so it's operating on whatever compatibility it has. I figured it wasn't fully register compatible, but I'm trying to try every possibility I can find in order to actually find what DOES work on a EGA/VGA/later card. I'll try out that tool and see what works. I see …

Sorry, I don't have any other suggestions. Your post covered anything else I might suggest. Unless you had any other Midi equipment (Keyboard, MT-32, whatever). If you do, I'd suggest trying that instead to isolate the computer half from the SC55 half.
