Ah I see why at 2.4Ghz you are worried that you are only getting 16k cycles/sec. However keep in mind that unlike the desktop CPUs where you can trust the frequency on mobile ARM you will be dutycycled and probably you will not be running at 2.4Ghz all the time. That being said you should be getting …

What ARM CPU do you have in that? Take a look at this (I know nothing about Android, I am more of an iOS guy, so this might not work) http://www.pixelbeat.org/programming/profiling/

I wanted to say thank you to both reenigne and Superfury for the work in untangling the correct cycle behavior of 8088 (and its XT bus). I am incorporating a lot of that theoretical information in CAPE.

Uff Gothic II Same story. About 30-40 fps @ 640x480 (but will all settings maxed) in the beginning (after you get out of the tower). Feels playable. I will increase resolution and see what happens and how it scales. Get a 9800 Pro or GeForce 6xxx for this game its highly recommend. I remember we …

There are few ways you can accomplish this. 1) VirtualBox. This games does not use 3d acceleration so VirtualBox would do fine. You will need however to find yourself a copy of Win 9x. 2) 86Box/PCEm. This will also work just fine. Like the above however you will need to source Win 9x. As for other …

How does the PowerVR Kyro II compare against GeForce 2 GTS? https://youtu.be/LuPuuCgciA4 One explanation for the Quake III's better performance (relative) to say Quake 2 is because at the time we used Quake 3 timedemo a lot as our benchmark in the OpenGL driver team to tune the Kyro's drivers.

So the Ti 4200 finally came (the Live! came too but I cannot get it to work for now). I am quite impressed with the results. I'll have some hard perf numbers soon but from a quick play around this is what I see Morrowind About 4x faster than Geforce 2 MX200. The interesting thing that I cannot …

Vladstamate: I think you're forgetting something. You say to substract 32 to get the actual cycle count, but it's supposed to be 16? The timings mentioned in the manuals are the 8086 timings afaik, thus don't include the extra 8088 4 cycles/word(the manual says to add 4 cycles to the already 51/52 …

Also more timings: INC/DEC word: 15** for memory(***7), 2 for reg. INC/DEC byte: 15** for memory(***7), 3 for reg(***2). If ** means subtract 8 then we both execute INC/DEC for memory in 7 cycles . This is execution only. Yes the whole instruction takes 17 cycles for an 8bit inc/dec but only 7 of …

Started to look at the timings again. I can explain why CAPE had 12 cycles for INT. INT (and INT3) Intel says 51 clocks (52 for INT 3). But that includes the memory transfers (which are not just simple writes as they involved stack address changes) So for INT x (0xcd imm) you have to fetch the …

The game was released in late 2004, so the configuration you plan (keeping it 2002 relevant) would definitely be considered outdated in regards to Doom 3. I agree with that. The system will not be able to play Doom 3 at decent levels. I am expecting around 8fps or so. I am just trying it for pure …

You can bump up the HDD and still be era friendly. It is actually 37Gb, but yes I see your point. It is what the machine came with. What is a good side for that 2001-2003 time? Not a big fan of the ECS motherboard or the chipset used on it, although by this point ECS had greatly improved since …

Oh, nothing special, just a battered old ATX mid-tower case. I tried putting a Geforce 2 MX 200 PCI in it and man, it is slow. Better than the terrible on-board SiS but not by much (about 10% in Morrowind, Gothic and Doom 3). I cannot wait to get the Geforce 4 TI 4200.

No, there is no VGA emulation in CAPE. However I am working on a rewrite of all MDA/Herc/CGA/EGA parts using a 6845 emulator. Most of the current issues in CAPE with 8088MPH are related to CGA innacuracies which this re-write should solve. Currently I have 4 individual emulations for each card …
