Can you not get it through your thick skull? I'm not interested in migrating. I have no use for it at the moment. I don't care. I don't want any compatibility issues with what I have.

In other words, stop trying to convince me otherwise.

My advice to use 64bit is solely aimed at ProtoKnux

The posts that you seemingly think are made to convince you to use 64bit is purely facts/opinions about the current state of 64bit computing.

Please re-read my previous post.

My advice was specifically to help ProtoKnux

And if he has more issues than the he wants? Really, an OS change doesn't magically fix stuff either.. only if the problem is analyzed properly before anyone should jump the gun on an OS change.

I never said there aren't any facts to support some of your claims, but I have no use of it at the moment. Even then, these are transitional issues that will be around for a while until it's pretty much solid across the board. The same thing happened in the past and I don't think it would change now (other than adoption might be quicker/better, but problems will still persist until it's ironed out).

Thats a choice he's free to make. He posted his main hardware specs and those all have 64bit drivers.

Well said.

I guess there will always be some problems. Personally i think we are on the verge of reaching that point. I have not run into a 64bit problem in a very long time (except for my laptop's scrollbar not working

)

Choices are fine unless you forget to mention potential problems. Once he complains about it not working as he would like it is not the way to go. When you propose an option like upgrading the OS, you have to at least mention the pros and cons of the situation. I could care less how much fluff you add to it, there is a reality to the situation and not everything is guarenteed to work as one expects.

You're right.

In that case, might be a good idea to disable (and grey out the Turbo Mode menu item) Turbo Mode when VSync is enabled.

Don't worry. It happens around here all the time. Just look at those custom alerts. They have been specially made for these ocassions.

Also, can Regen have both versions of VSync too? Sync To Audio and Sync To Video, just for the fun of it?

Garghhgdhh.h....

I'm pissed off... same results!

But now I have discovered something. I have tried the latest official drivers from NVIDIA and the results with Gens were different than the XG ones (modified drivers, they just run better on 3D games, I can confirm that). Yeah, they were different, they were EVEN WORSE. I think it's some kind of crap they actually have on the latest drivers, the 2D acceleration is fucked up or something on 7xxx series. I would be grateful if someone uses a 7900 GT Golden Sample (overclocked by default) and says which version of forceware drivers is using to get emulators working. There's one thing for sure: With the official drivers, if I change to full screen the FPS meter goes to 75 fps and the screen is a bit uncentered. And when I change the filter, it crashes. Creepy.

OK, I didn't mention my 7900gt needs external power and I connect it with an adaptor with 2 of those IDE connectors. But I think that should be right.

Now there are only 2 things remaining: the graphics card or the OS. Don't know what to do.

EDIT: Oh, anyway, I'm not upset about spending like 200$, because I need this for more reasons. I don't have this PC just for emulation.

Using Regen? Not using a graphics plugin past a scale 2x right?

No, no, using Regen it just does the same thing (frame skips) not at the same rate but it just does the same thing. I meant Gens. Regen is a great emulator, but it does that. I don't mean that emulator is bad or something, it just doesn't work like Gens. Perhaps because it doesn't have any frame skipping option (haw haw haw).

Anyway, now I'm confused. Perhaps is the OS? I know I've been using the same for a year and I would need to find another copy, probably. Or changing to x64, tetsuo could be right (no bad feelings, ok? I can't say it works better or not because I have tried it just once and without driver support years ago, I accept everyone else's opinion).

King Of Chaos · Post by **King Of Chaos** » Mon Sep 08, 2008 8:13 pm

Well, then again, Gens hasn't been updated to work outside of a 16-bit color environment. If you're going to use Gens, then I suggest giving Gens+ a shot over the original Gens (it's better). But the best overall Genesis/Megadrive emulators are still Kega Fusion and Regen.

About the frame skipping issues, sounds like a crappy graphics card. Personally, no issues here on a low end ATI card.

The OS wouldn't really make a difference.

You did change the mobo, right?

Yep, right now I have a Gigabyte GA-MA770-DS3. The results are exactly the same, so... the only thing I suspect it is: the graphics card. But I won't buy another one. It just runs fine and is not old/crappy enough to have that kind of problems anyway. I think is just the drivers. Why? Well...

We have 3 PCs. Every of them use AMD 64 processors.

My PC = 7900gt = modified or latest drivers = genesis emulators won't run fine

My sister's PC = radeon 9550 = latest drivers = same problem

My father's HTPC = Integrated radeon X1250 with hdmi support = drivers from cd = it runs flawlessly

This is plain stupid. I mean, if there is a chance it won't work because of up to date drivers, then NVIDIA and ATI suck dick them both. I don't know how to make this clear, but I won't just downgrade to 94.xx versions, they are outdated as hell and I play some actual things too.

Yep, I got one of these on one of my other computers, and I find it works perfect too.

It "seems" that some part of your system has a few MS lag, after a while the emulator syncs up causing either tearing or crackling.

The cause of this problem could be many. Trying 64bit is an option but i think there is a better solution

-Troubleshoot your problem like an IRQ conflict (use google)

Nope hes still completely wrong.

REGARDLESS of the alleged 10x 2D speed benefit provided by 64-bit, you're still wrong in your claim that most emulators have selectable 2D/3D modes.

ProtoKnux · Post by **ProtoKnux** » Tue Sep 09, 2008 11:38 am

Ok guys, I've discovered my integrated realtek hd sound card has a high latency and I have soluted that with a CMI8738, is a piece of crap but still I don't have latency problems with it. But... I have still the same problem. Explain that, jesus christ... it doesn't make any sense. Ok, I have no IRQ conflicts, but my graphics card is sharing the IRQ 18 with my integrated ethernet card, and 2 USB ports. To ensure things, I have installed XP SP2 without installing SP3 after that, and I have nothing. This is pathetic, do I have to enable the extension limit on the Nvidia Control Panel? Do I have to underclock my graphics card? Do I have to buy a fucking Megadrive? (I had one but I don't know where the fuck is it)

Which one's don't? i thought most did, the option is not always obvious to find though

IRQ18 is a shared IRQ. There are only 16 IRQ's (0-15). ACPI allows the mapping of shared IRQ's on i think 9, 10 and 11. So 16 and up are all on one or more of these 3 IRQ's.

IIRC, there's something that is used to extend the # of IRQs available (another 8 IRQs are available).

Found it.. it's the ACPI APIC Function... http://www.techarp.com/showfreebog.aspx ... &bogno=363

ProtoKnux · Post by **ProtoKnux** » Tue Sep 09, 2008 4:13 pm

That's what I get.

Anyway, tried x64, doesn't make a goddamn bit of difference. So that speed benefit is bullshit. Sorry about it.

That means... is the graphics card. What should I do?

About that APIC function, I don't have it on my BIOS.

Deathlike2 · Post by **Deathlike2** » Tue Sep 09, 2008 4:38 pm

Yours is probably already on since ACPI is enabled on your system.
