Whoops, sorry, I didn't know the exact function of the "~" character here.

4x resizing needs loads of memory and the memory usage will increase with each new texture / sprite you see. It's possible that you simply don't have enough memory for this feature. If there are enough textures on the map it's possible that you need 1GB RAM or more.

My laptop (where the crashes occured) has 4GB RAM, but I think 32-bit apps cannot allocate more than 2GB? When I was playing, at the start Zandronum was using like 200MB of RAM. After approximately three minutes, I looked in task manager and it was using 400MB! Then, each three minutes (or like this) the memory usage was increasing by ~ 200MB. Most likely it reached (or tried to reach) this 2GB point and Zandronum crashed. I don't think it is supposed to continuously increase its memory usage by such a high amount.

I can use the hg resize modes without problems, so this may also be a bug of your GPU driver. Which GPU are you using?

I have the same issue. I'm using HQ4X and in maps/wads with lot's of effects (like stronghold) more and more ram is used until ZAN finally starts running at 1 fps. However, alt-enter (going from windowed to full and vice versa) fixes it and ZAN runs fine again.

Frits, which GPU are you using?

My laptop's GPU is GeForce GT 540M, IIRC (I don't have it here with me). My friend, who was experiencing high usage of page file, has a GeForce GTS 8800 512MB. We both always use the latest official drivers.

Check if it happens in gzdoom, if not then report back here

Which version of GZDoom should I use for testing?

Try the absolute latest and see if its fixed

I wasn't able to get the very latest GZDoom build to crash.

Zandronum 1.2.1 still crashes though. The easiest way to get it to crash is to load a mapset with lots of new sprites and textures - I used Armageddon 2 Invasion MAP09 for testing and it crashed somewhere in the middle of the map.

High memory usage is clearly seen when using scale4x, independent of the mapset loaded. With "High quality resize mode" turned off, memory usage doesn't go higher than 200 MB; with scale4x enabled, it almost immediately jumps to 300-400 MB, then continuously increases during the gameplay, and eventually Zandronum crashes. It does so even in single-player games.

I can confirm this is most likely an issue in the setting as opposed to the user's PC. I've been using the high quality resize mode on textures and fonts and after roughly 50 minutes of gameplay in the All Out War server my client crashes with the "failed to allocate" memory error.

My guess is that the resizing of the fonts cause the overflow for me since the texture are static and never change. With the fonts, you have in-game frag messasges, player's chat, menu fonts, etc.

Given that the user stated he couldn't get the latest GZDoom to crash (1.8.6) at that time, 3.X should have the same behavior. If someone still has this crash with 3.1 or 3.2, reopen the ticket.

This issue is already marked as resolved. If you feel that is not the case, please reopen it and explain why.
