edit: Well, I decided to just go look it up. According to the always-right wiki your board uses a 430VX chipsetted board (unless of course somehow the original motherboard got switched with something else). How did you crap 128MB of SDRAM into it? I've understood that people who try to put a 64MB …

Re: Which is faster? U5SX 486-33F or TX486DLC/E-40?

As you can see from the results, the UMC 33 MHz CPU is somewhere between your Intel 486DX 33 MHz & an Intel 486DX2 66 MHz. When I tried a socketed UMC U5S I found the same so the CPU itself is potentially faster than a DLC and even an Intel SX. On the other hand once I found a relatively intact ( …

The slowdown with translucency is very odd; of course similar things happen in the Doom engine but they don't seem to be GPU dependent. I don't even try to understand Doom. Its performance above ~ P2 class is a complete hit and miss. "Luckily" it's limited to 320x200/35fps so it's highly …

Now J I know it's possible to run Blood (or other Build games) 1600x1200 on a P4, because I am right now! Except for no sound under DOS, it's perfect and never drops below 20 frames. I have right now a 3.0/800 Northwood and dual-channel DDR400. If you can only barely get 1024x768 on your fastest P3, …

As for Blood 1600x1200 - it seems to me that a regular P4 wouldn't help at all. I've tried this game on P4/ISA (a 845 based Robo-8712VLA board with a 2.8/533 Northwood CPU and 2x1GB of DDR running at 333MHz), Tualatin/VIA (1.4@1.5, CL2 SDRAM) and SocketA/KT133A and I could make it work on all three, …

I made this 100x times and never damaged anything. For the 30 pin you usually need 4 of the same kind. If you have 3x1mb and 1x4mb it will display 4 mb ... not 7. So for your test setup install the largest simms you have and exchange only one to test. 386SX and 486SLC have the "edge" here because …

So USWC gives you the 100% performance boost? I don't think I've ever seen USWC on a motherboard as old as a socket 8. Was this common on socket 7/8 boards and my supply set is just too small? I have always left USWC disabled because of internet comments of instability, and possible (marginal) slow …

Useful link, thanks, robertmo ! So the Ivy Bridge i7 is at least 35% faster clock-to-clock (if the i7 ran in Turbo, which is possible most of the time because most of the DosBox load is on a single thread: a single threaded application through a JIT compiler) here than an older Phenom. Which is …

I agree. A newer build would be good. Of course the most interesting part is the dynamic core. What I know, my old Core2 Duo (Conroe 4M, overclocked @ 3.1GHz, with DDR2-800 and a Radeon 6670) can do like 92fps with quake timedemo1 in 320x200, run in a 2013/04 Ykhwong build. But I don't know anything …

Yet it seems either VMs weren't in focus when they made the Bulldozer design, or there's something in DosBox in particular, but this doesn't only make BD ugly, it's a complete disaster: http://pctuning.tyden.cz/hardware/procesory-pameti/27079-intel-core-i7-4770k-ctyrjadrovy-haswell-do-desktopu?start …

I have a somewhat different question: has anyone studied how new architectures work with DosBox? I remember that in the old days P4s were miserably weak under DosBox compared to the AMD lineup. Later the Core CPUs became good at DosBox, and lately it seems that AMD Bulldozer and its successors are a …

Not games are VESA HC/TC, but many demos I like to watch. On Gulikoza's builds: I am one of those who experienced stability problems with Ykhwong's most recent builds switching to fullscreen and back. Pity that Gulikoza builds seem to be ~10% slower. I don't know the reason, but it shows on Blood …

Good question, especially now that Ykhwong has disappeared :( And direct3d is the only output that seems to be able to do full-screen, aspect correct high/true-color VESA modes. (But if anyone can advise how to set up all of them (not just one, fixed resolution) to correctly fill an approppriate …

No, it's not enough. There should be some 'wrapper' around just like DosFreak wrote... I've tried something (opnGLide, if I remember well) but nothing changed - how on earth do someone use this kind of thing? 😖
