So if I read this right this was only impossible because their old D3D implementation didn't use a proper implementation, and as a result it saturated intermediate results. Quite... It all sounds horribly clueless, and pathetic, which is no surprise, since it is being spun as pro-OpenGL. I always …

Re: No FM synthesis output from sound card

However, my problem is related to the FM synthesis playback (there is no sound) which is normally via port 338h (I don't have an option to change this anyway). Yes, the original Adlib was fixed to 388h, and so Adlib-compatible cards don't usually allow you to configure that address either. For OPL3 …

The only one to have had native Linux support for year s (plural) is Source (and indeed almost every new game released with it is compatible. Perhaps not many AAA though) UE3 always required some low level tinkering (and external ports usually made by Aspyr or Feral). UE4 on the other hand added …

Yeah I do remember it was really expensive even the 30 pin simms when 72 pins were already released.I remember that when I saw the counter on the 386 that had 16MB of ram running at boot, it was unbeleivable to me... Must have been a high-end board. My 386SX-16 simply didn't fit more than 5 MB: 1 …

In my case: 386SX-16 bought around 1990 with 1 MB of RAM, expanded somewhat later to 5 MB. 486DX2-66 bought around 1994 with 4 MB of RAM, expanded to 8 MB later (currently 16 MB, but that doesn't really count, it's a single 72-pin module that didn't even exist back then). Pentium 133 bought around …

I believe more AAA games have been released for linux in the last 6 months than in the others 23 years and half combined. Still it's not a whole lot compared to what's being released for Windows :) If you consider newer Cryengine, Source, UE, Unity versions all natively support linux.. Some of …

The CL should be quite good, and the ATI is probably also decent. The others I would stay away from.

Why its not possible to setup dosbox to work like pc with, for example, Pentium 166? And forget about clocking cycles every time for different games on different PCs? That would require big changes to the emulation core of DOSBox. Currently it counts all instructions as 'one cycle'. In reality, …

By the way I didn't think that ATi cards were not as fast as we later knew for the (PCI maybe not but) AGP cards. I see that there're many ISA cards even 8 bit built by ATi and I was actually tempted to buy one. ATi's first decent videocard was the Radeon 8500. Before that it was all pretty bad :) …

Yes, my philosophy is that if there's not a good reason why it shouldn't work, then it should. And in this case I think I can get it to work (the thing is mainly that the processing speed is critical, worst case I could shave off a row of scanlines to speed it up and make it fast enough, but I'd …

There are some wrinkles there. A big one is that DirectX is a proprietary "standard", so you're completely dependent on the Wine team's ability to interpret and translate the DirectX API, which will never be perfect as long as Microsoft hides the internals, and may not be up to date enough for AAA …

You may have to install/update drivers for your motherboard's chipset first. It could be that the chipset is not properly supported, and therefore the PCI-e bus is not working correctly to detect your video card. Another reason why NVidia drivers may fail to install is not enough space on your …
