No problem. I am glad to help. I think I further narrowed down this issue. I have found that when switching to windowed mode and moving the Mac mouse cursor rapidly, there is no slow down in the audio. However, clicking back into the DOSBOx window and repeating this with the DOS cursor does cause …

The Core 2 Dup Macbook, does it behave better with the 0.74 release of DOSBox? Good point. I tested TIE Fighter at SVGA resolution in the 0.74 release on the Core 2 Duo and it works fine. Switching back to SVN 64 bit and the frame rate drops so low it basically hangs. So that one was definitely a …

in general core=dyamic gives you the best performance. Core=auto will switch automatically to the needed core. Dynrec means the same as dynamic, in 64bit this is slower. Thanks for clarifying that. :happy: Generally, I am finding that the slower performance is not noticeable on the i7, and even on …

I take it that if I am testing with the SVN snapshot by Dominus (or the gs11 build) and use core=dynamic in the dosbox.conf file, then I am using the dynamic x86 core? I am finding that core=dynamic is working for most games and there are only a few older ones that require core=normal. It sounds …

I have been testing 64 bit DOSBox (both the gs11 and SVN build by Dominus) on a 2013 Haswell i7 iMac with NVIDIA graphics, in High Sierra 10.13.4. I have tried a range of games and they appear to suffer no perceptible slowdown, including a bunch of Sierra AGI and SCI adventures, Rebel Assault 2, …

Ok thanks, that works. Sorry, I won't post anything in relation to abandonware again. :oops: BTW: I do know how to do a DIR command to find the executable files. I just wasn't familiar with having to modify the command line to change sound drivers - I hadn't seen that in any other DOS games I've …

Thanks. I'm using the one I got from HOTU. Can you tell me exactly what to type at the command prompt?

All the reviews of this game say that it supports MT-32 and Adlib sound. Is there any way to get this to work in DOS Box using the sound blaster emulation settings? I can only get the game to run with PC speaker sound.

Sorry, I should have mentioned that I am using an image of the game - I don't have the actual CD in my drive. For the record, the problem occurs either way. Don't know what else I can do to tweak sound settings. It happens with both SB16 or SB Pro specified. It's hard to tell whether its actually a …

I am experiencing an annoying sound problem with Dark Seed 2 (CD version) running in Windows 3.11 on DOS Box 0.72 Specifically, the first few seconds of every individual "segment" of voice audio will stutter, and then the rest of the segment will play normally. I do not have performance issues with …

Couldn't that be addressed by labeling it as: Original (as game will request)

Aha! "Fullscreen=original" seems to have fixed the problem. ...at least in full screen mode. DOS prompt: http://www.eftel.com/~almeath/temp/dosbox/dos3.jpg In the game: http://www.eftel.com/~almeath/temp/dosbox/dos4.jpg I still get the "shrinking" window effect when playing a game in windowed mode, …

I just tried setting fullscreen=original in the prefs file, but there is no change unfortunately. fullscreen=original fulldouble=true fullresolution=1280x1024 windowresolution=original output=opengl aspect=false scaler=hq2x forced

I'm glad this issue has generated a lot of discussion. I'll be trying some of the things suggested and post back, but in the meantime, to help illustrate the problem, I have attached some screen shots. (1) My graphics settings in Dapplegrey (note: hq2x scaler is "forced") http://www.eftel.com/~ …

I've been able to partially fix the problem by editing the preference file. By setting an 800x600 resolution and then forcing hq2x, I can get a larger graphic smoothed image in full screen mode. But it won't take up the whole screen on my 1650x1080 display. I get about a 3 inch black border around …

I am using: - DOS Box 0.72 - Dapplegrey front-end (latest version) - Core 2 duo iMac with Radeon HD 2600 PRO graphics card - Mac OS X 10.5.2 Scaling/rendering is not working correctly either in full screen or windowed mode. High quality rendering options such as "HQ2x" have no effect when in …
